Yes, please do show the process of restoring the PACO C-25 capacitor tester. Thank you for all your very informative and well taught content.

While out at a garage sale resently I scored a Weller D550, SP80, SP23 and a colossal "American Beauty" 600 watt, model 3198. All for only $25. And they all work! Not sure what use the American Beauty is for but it was a package deal. Your videos have inspired me to restore my 1930s vintage Wards Airline radio phono. Now I have the tools and parts to recap the radio. Thank you Mr. C for sharing your knowledge!

WE need more videos on how to test and use your favorite capacitor testers. This way we can equip our Test Benches at home!!!

The Heathkit IT-11 tester was the 1st serious piece of electronics i handled in my new job after leaving school and becoming a "Tech Trainee" for an AM Radio Station. My head supervisor bought the kit for peanuts as the local agents for Heathkit were having a huge clear out sale.. It was 1978 and tube based gear was classed as having done it's day. I completed the cap checker build in a couple of days and it worked perfectly first switch-on. It then sat on a shelf in the workshop for the next 5 yrs because the company was systematically replacing all its studios with modern semiconductor based gear. One morning I came to work to find a huge dumpster outdoors full of various 19" rack mount equipment, all tube based audio gear that had been the sort of thing i'd been trained on and sitting ontop was 'my IT-11'... never to be seen again.... BOY I WISH I HAD "RESCUED" IT THAT DAY....

Great to see new content from you Mr Carlson, enjoyed every second of it.

This video answered literally every single question I had regarding testing capacitors.

I'd absolutely love seeing a video on restoring the cap tester! It's fascinating to learn about the inner workings of these pieces of equipment through your amazingly well done restoration vids.

Clear and concise. A very well-made video. We appreciate the time and effort you put forth to share your knowledge!

I always look forward to your restoration videos.

Love the vintage equipment restorations, could watch them all day! 👍

A huge thumbs up Paul. Yes, I for one would love to view detailed circuit explanations regarding each one of the of capacitor testers: especially the older types. Thank you, Phil.

I learn so much from your channel. You have a great way of explaining and demonstrating things.

Many thanks for another great video. Some time ago I bought a Sencore LC-102 capacitor/inductor analyzer. It can perform tests for capacitance, ESR, dielectric absorption and leakage. It is surprising how many caps I've thrown in the bin because they tested bad for dielectric absorption, but good on all the other tests. My whole collection of old Jensen paper in oil caps had very bad dielectric absorption and were tossed in the bin. Also I've found quite a number of ceramic caps that tested bad for dielectric absorption.

always gaining an in-depth perspective in test work Paul. Nice video thank you

Love the crystal clear explanation of ESR! And please do the Paco restoration video. I will happily watch any restoration video you post.

Your lab is so amazing! I hope one day mine is half as impressive as yours. Thank you for all the videos sharing your experience and knowledge. Your time is very much appreciated.

Very timely and informative. I've been needing to make a decision which testers to buy, and this helped me make my choices. I had been doing blanket re-caps on anything over 40 years old, and power supply''s on anything 30 years old ( audio gear), but I want to test the electolytic's to be sure I get all the shorts as well as leaker's.

Absolutely amazing to watch your videos. Totally new in this field, but I still enjoy. Wish I had the time left to learn. Anyway thanks. Rick n WV

Thank you for another great video. Covered all aspects of testing Capacitors. I really like the leakage test as that's one thing I don't have in my workshop yet. I have the ESR testing etc. Keep up your well planned and produced, educational videos. Thanks.

Thanks for the fine tutorial Sir. I've been restoring old American tube radios for years and thought I had all the bench boxes I needed, but I'd never even heard of the ESR test. (I never claimed to be a "good" restorer!) I'll be expanding my support gear collection once again, as soon as I can locate one like you use. I'll soon have more gear than radios!

Mr Carlson great instruction vid, thanks for your dedication to teaching.

Always look forward to new videos, Paul. Please do the PACO C-25 video.

Would like to see the restoring of the PACO C-25. Thanks for the videos.

That would be interesting to see the restoration of the first tester you showed. Love your channel and your content.

GOOD JOB. Thanks for your time. Would like to see a series on spectrum analyzers old and new.

Wow, I have got to say that I am super thankful for all this in depth information! It has helped me understand a lot!

Shopping for a capacitance testor, and I'm so glad I saw your treatise on devices. Thank you!!

Geat presentation. I know next to nothing about electronic circuits but was able to follow your precise and well articulated discussion.

Great coverage of cap-testing methods & fundamentals. A closer look at the PACO C-25 would be great. Thanks for this informative video!

Expertly done- as usual, Harry

Allways interested in opening up test gear and seeing how it works. Good video as usual Paul.

Also, please do the restore. I watch your restores even if I will never own the equipment. I always learn something new.

A video of refurbishing the Paco? Yes, please! Also, this was a very informative video, thank you very much.

I just found this today. Very informative and I hope to find more of your videos. Thanks

It is so nice to see other electronic 'geeks' supporting each other and saying such nice things about Mr Carlson, I particularly and wholeheartedly agree with Soundscapes first paragraph below. These uploads are a true joy to watch and so clear and precise. It makes a change from other channels, where all one sees is bickering and backstabbing. But then we techno geeks have a bi-product to our respective intelligence, we are gentlepersons. :-)

As always, excellent. Clear, concise and very educational.... Thanks for your efforts.....

I can't even tell how much I'm learning. Thank you.

Your videos are incredibly amazing. Keep it up.

Very good info, it's what we all need to know to be effective at repairs. I was never given this info, never shown how it works on various testers, and it's a real good safety measure as well.

I will watch for the restoration mentioned. Thanks for the instructions on safety.

Great video!I learn a lot watching your videos'!Thanks' for sharing your wealth of knowledge with the rest of us! : )

loved the video. I have the Heathkit I'm restoring now. looking forward to using it. Thanks for the lesson.

Paul, always great to watch your videos. Best regards Victor

Thanks so much for doing this video on capacitor testers. I have both the Heathkit IT-11 and a brand x ESR meter that I've never known how to use. Now I will be able to delve into my old Heathkit Shawnee 6M AM rig and, hopefully, get it working. I will be eagerly awaiting more videos on how to service old equipment.

A must see video, as usual! Thanks!

Very informative and a pleasure to watch! Yes...please do a video on the Paco! Hope you find time to do an in-depth video on the Heathkit IT-11, covering the Power Factor test. Thank You!

Love to see a video on the Paco c25 Paul looks like an interesting piece... we use the Heath IT11 here at the Audio Workshop after watching your first video on using it. Keep up the great work were also a Patreon supporter...73's

As others have said, you are a really good teacher.

Fantastic video. Thank you for the info. Just needed to test my old amps and there are no shops near me.

You blow my mind, Excellent explained and presented !

Brilliant! Much appreciated by this student in his ity decade 😀

Awesome kind Sir Paul. You are a great instructor. Thank you.

Warmed my heart to see the EA (Electronics Australia) ESR meter in your video. EA was a fantastic electronic magazine!

Hello Mr Carlson, Im brand new to electronics. Have just started to play with a bit of stuff lately (DC only AC frightens the hell out of me) and found your channel , By far the one i have liked the most so far. Quality information from an extremely knowledgeable person. 1 week and I can now tell what most small part are thanks to you. The most important thing i have learn in 1 week is you must have a damn good memory, Im mean someone like you its all just their in your head you have done it so much, But when its just a pass time hobby that you do maybe once a week to a mth lie me you really got to put some effort in to remember so much. Things like reading the colours on resistors , and pnp npn stuff and chip pin out info like a=1 b=2 c=4 d=8 etc . Very easy when you know how and you are right why they didn't use just positive and negative can only be to confuse those who are not in the industry, thats fine thats what learning is all about and all industries do it.. Im finding it extremely interesting but difficult to remember so much when you do it so little. Brilliant stuff from a real tech with quality and safety in mind. Your knowledge is astounding and extremely well put so dummies like me get it. Thank you.

Nice video. With the scarcity of testers like the Heathkit for doing leakage test, a nice project might be to design a leakage tester for folks repairing/restoring old tube gear.

Excellent demonstration; informative in multi purpose usage of a variety of capacitor testers. Like many others, more than one tester is a must, considering the multitude of electronic devices that need attention and capacitors are the leading component failure in most equipment, "nicely done"

Always a pleasure to watch Mr.C's videos. My test gear knowledge must have peaked about 1974. So, this really helps ! Today, one can get fine test new ( Chinese) test gear for less money than obsolete American stuff. But some of the old stuff remains invaluable.. as we see here with the Heathkit cap checker used to test leakage. Bravo..

Great video. Learned a lot. Thanks!!

Thank you for the excellent capacitor testing video! I would love to see the Paco C-25 video too, they made very good testers also.Louis

These are absolutely fantastic videos.. many thanks for doing these

Great video. I didn't know which one to buy, I know now. Thanks

Great video, the approach you demonstrated with leakage and ESR testing has amply demonstrated the inadequacy of testing only with low voltage device that only gives you a capacitance value. For my own bench I am have a Sencore LC53.

You are such an incredible teacher, thank you!

really excellent video Paul... as usual...

On the Heath cap checker,, My first day on Adak Island the ET spaces in the Navfac, I was tossed a big old electrolytic, and I made the mistake of catching it. The shop had a great laugh as I cussed like the sailor that I was. Great Memories, and one that I will never forget.

I'm not an electronics novice, and I found this video informative.

Great video on testing caps . Thanks For Sharing

Thank you for this video. I learned a lot.

Excellent video, very informative and educational.

I own one and will be restoring it shortly. I’d like to see more.

excellent tutorial , thank you for posting!

Another vote for videos showing how to and use the old test equipment and what to look out for. I am in the process of putting together a test bench to restore old radios and will use the older type of test equipment like you have shown. Enjoy all your videos, have picked up a lot of great information from them. Thanks for taking the time to do them.

Keep up the Good work and Thanks!! : )

Great stuff as always. Thank you.

Hi Mr. Carlsons; You have the gift of answering my questions before I ask them :-) Thanks. L.

I don’t think anyone here on youtube can guide me to another youtuber who’s even close in knowledge to Mr Carlson.

Great video and it looks like I have some additional test equipment to buy now :-)

It took me years as a youthful hobbiest in electronics to understand the vagaries of capacitor evaluation. Interestingly it was AC induction motors that helped me appreciate ESR which was before the days of switch mode power supplies that of course would have done that also. All I had a kid to test with was an Argonne multimeter not even of 20K/V sensitivity.

Thanks for the informative video. I have the Heathkit IT-28 tester, and I consider it and my ESR tester, as two of my most important test instruments, as I am always fooling around with older tube type equipment. The big problem I am having with the IT-28, , is the colour in the eye tube is washed out. It still works properly, but it is more difficult to see what is happening.

Brilliant video! Thanks for this A+ lesson.

+ my vote on the rebuild video, I enjoy all of your rebuild videos.

I would love to find one of those Heathkit testers, or at least build a copy of its leakage circuit. Thanks for all the great work Mr Carlson!

Yep... please show the restoring of the PACO C.25 capacitor tester Mr C. As always Paul very much enjoyed this vid, nuther snippet of knowledge gleaned. Thanks Graeme

Thanks for showing the differences between testers, it was very informative.

Yes great showing different gear and test results. I have an old Sprague cap tester with an eye tube, it would fail to open on the one capacitor on my Tube Tester. Pretty Cool. thanks for the demonstrations very well worth the time to make and watch. D

I would like to see the restoration of both of these meters, should be interesting. Oh and please show us your time machine ;)

Very nice range on Cap testers. I use a Megger insulation tester to check for cap leakage as well as my old Solar, Hp4261a and Racal Databridge. They all have their pros and cons.

Nice information. Thank you.

Nicely done, I loved the Heathkit tester

I'm always interested in your restorations. Please do.

For years I used an (analog) ESR meter from Creative Electronics when I lived in Michigan (where they were made). I wish I had one now. Saved a lot of time troubleshooting.

Did any other Australian viewers notice the 'EA' logo on the ESR and Low Ohms meter? - it's Bob Parker's design featured in the January 1996 edition of Electronic Australia magazine. Also, count me in on a PACO C-25 restoration video too...

Excellent video! Thank you very much. Would love to see the PACO C-25 restoration!

Nice collection and useful information. Thanks again to share this masterpeices images with us.

Absolutely loved it MC. Yep checking ESR is essential on any suspected or reusing an old capacitor. I find it very useful in checking a computer motherboard or power supply capacitor. Thank you very much for the nice video. Best Wishes n Blessings. Keith

Great video, would love to hear your thoughts on curve tracers and scopes with built in component testers for testing capacitors.

Dear Mr. Carlson, thank you for making and posting this very informative video. I learned something. Thank you. t\.

Ditto on the restoration of the PA-25🔍☕️📓

Great video, thank you!
