I loved Pioneer equipment, all I have left of my old Pioneer equipment is the PL50 turntable I purchased in Vietnam. I used to have a Hitach AM/FM/Cassette recorder/player combo but some prick stole it when I went home for the birth of my son in 71. Best damn radio I ever had.

I bought my 1st stereo system in late '70's at a chain. Wanted to hear the best from my phono collection.. Pioneer. This receiver is incredible.

Perfect viewing while we are all in self-quarantine.

One more of Mr Carlson's video to enjoy and learn. I hope one day, Mr. Carlson take on a The Fisher 80T hi fi preamp and AM/FM tuner and also a The Fisher 80T amp. I've got both from the person who restored and aligned them. He made a great job. But it's never too much to know more about your favorite equipment.

Why would any one want to put a thumbs down on this guy. He is so good at what he does and he is willing to explain what he is doing to whatever level of expertise you are trained or knowledge you at. I have never seen a video I have not liked or gained knowledge from. Keep it up.

What a huge amount of effort that went into designing and building this unit. Magnificent.

Used to have one of these....love the magic eye gimmick ;) restoring a pair of Marantz monoblock amps found in Dad's garage while clearing it out for sale tubes light up so far ;)

I wanted to say how much I enjoy watching your videos. I appreciate the way you explain things, share your knowledge and experience working with different components over the years. I studied electronics back in my college days and have spent almost 40 years in the IT business. Thank you.

A special thing about Mr. Carlson's Lab, almost everything I have watched, except for your inventions and other test equipment, are older than me. I'm not young. I enjoy seeing how you transform a rats nest of wires and components into a nice logical layout. My very earliest years, I do recall my father working on a TV with tubes, and taking several tubes to Thrifty's to test and buy a replacement or two, but that's about it. These radios "belong" to our grandparents. They are fascinating and it's good to know they can still be serviced. I would like to see an evolution of electronics, documentary/special, where you cover the design and components of the earliest radios to modern times. What technology will likely last the longest?

After watching one of your extended play videos wherein you repaired an amp, I was excited to watch this video. Fascinating suff. All receiver, not face time. All receiver, not snowflake sound effects. Not a made for tv reality show. I love high end receivers. There's nothing better than super loud music with no distortion. Audiophile vs Van Halen. My ears are still ringing.

I still don't know we love receivers this much!!? 😊 Thanks Paul for this share!

I am an old guy , it is wonderful to listen to you. Just don’t have the drive to learn electronics. But sure a great sense of curiously

Paul, stay safe, stay healthy and whatever happens, keep breathing!

Interesting. I have a H. H. Scott AM-FM stereo tuner that is similar to this receiver. It has the separate AM and FM tuners for simulcast stereo, but it is also decodes FM multiplex for true FM stereo. This tuner hit the market just as FM multiplex was coming into use, H. H. Scott being one of the pioneers in this technology. H. H. Scott also sold standalone FM multiplex decoders for use with older FM tuners.

I love this reciver, those caps often go dry ,become dried sludge and the Japanese stuff from the 60's are so well roll crimped that they dont leak very often. Very well made stuff. Please restore this tuner,Don't cast it to pile .I was so happy at the end to hear it will be saved.

I’m still patiently waiting to see the restoration on this one!!!😊😊😊 Gonna be AWESOME!!!

Mrs Carlsons lab your vintage pioneer tube receiver from the 1960s is awesome my friend 😅😅😅

In the era just before stereo MPX FM, (late 1950's) these dual turner systems were popular. My mother did "traffic" at a small am/fm station and said one of the DJ's would come in on saturday morning and do a "stereo" show. This was accomplished by feeding the output of a stereo phono preamp to the am mono console and the fm mono console. This must have been very difficult and one channel was very low fi. Stereo was clearly a novelty then.

Oh boy a Pioneer SM-B201! It's in fantastic shape! Very worthy of a rebuild by Paul Carlson! In early days of stereo a radio station would send a signal to both an AM and FM frequency using two separate towers. One channel was on AM and the other was on FM hence you would get a stereophonic effect. This was expensive for them to do this and was a very short lived idea. I love anything with "magic eye" tubes BTW!!! Look up Fisher 800-B to see a the competitions version of this kind of receiver The Fisher 800-B had 22 tubes to do what the Pioneer did. But it also supported true multiplex stereo FM of today!

Mr Carlson your vintage pioneer shortwave tub receiver from 1960 is cool

Way back in the 60s I used to repair a lot of PA amplifiers, many of which used EL84 tubes (6BQ5) in class B push-pull. Those wax capacitors were terrible as you say and when they leaked onto the control grids of these tubes it would often write off the mains transformer as well. There was a problem with the tubes themselves though. Most were Mullard, a usually good make, but the EL84s used mica separators for the electrodes and the mica would gradually break down and cause the same problems as the capacitors, but in this case caused a leak between the screen grid and the control. The solution, after a great deal of experimentation, was to replace the Mullards with a Japanese make, Pinnacle, which used ceramic separators. I have no clue who actually made Pinnacles (maybe someone here can enlighten me!). Solved that problem completely!

Very nice Pioneer receiver. Pioneer has always been one of my favorite electronics brands over the years. The best "bang-for-the-buck" there is IMHO. I previously owned many Pioneer car stereo systems, and I still have 2 Pioneer surround sound receivers (and speakers) , as well as a Pioneer turntable. I have never had a Pioneer product fail....ever. Yes, there are more expensive "designer" electronics brands, and even better sounding systems, but for the price Pioneer cannot be beat.

Just want to thank you for being there with these videos while so many of us are stuck at home. You are really fulfilling our electronics geek needs.with all you know about electronics I'm surprised you're not Dr. Carlson at this point!

What an absolute gem. Looking forward to this restoration.

My brother in law had one of these SM-Q140s purchased around 1967 (it was a showroom demo), with a deep blue enamel in place of the black. With a set of Rectalinear lll Highboy speakers it sounded fantastic. I now have those speakers and they are used every day with my Kenwood KR-A5520 receiver. I had to replace the output transistors & main audio power supply filter capacitors for the Kenwood. I ordered the filter capacitors from China. I needed only two so I ordered four of the filter capacitors, as usual. One of the four "new" capacitors was an open circuit, which is why I "over order" from Chinese suppliers.

Capacitors, as the age become leaky... Guess I'm an old capacitor...

The engineering that went into this is amazing!

That is one gorgeous receiver... great find!

Mr Carlson you are positioned to answer this question better than most electronic engineers: simply speaking , “ how are they (receivers) all different from each other”? What does one brand use in its design that other brands do not? Could also be asked “wherein does the quality lie”?

I find this an exciting project. This is certainly a unique receiver that needs restoration. So purely analog.

That's an awesome receiver Paul. I work on a lot of audio equipment and I think that is the earliest Pioneer stereo reciever that I've seen. Very cool. Thanks for sharing it!

As busy as that unit is, your camera angle of it would make a neat shop poster.

What a lovely receiver.

thanks for sharing your expertise.

Hey Paul thanks for these videos

The stuff you find is just amazing!!! Thanks for sharing!!!

I have a Pioneer/Allied SM-G204 that is similar to that one .Mine has been restored and i love it. Sits right beside My SX-1980 . Love the old pioneers

This is awesome. I found this exact receiver at an antique store a couple of years ago. Very little information out there. It didn't sound the best but everything worked well and it looks like new. I listened to it for a couple of days haven't powered it on since. I'm anxious to see the restoration and to hear your opinion of the sound when you get it sorted.

Who gives this a thumbs down ? ? Thanks for the video Mr Carlson

Just love listening to his commentary and knowledge. Every video is a learning experience.

Nice to see a video from someone with a really good camera and microphone. Plus good lighting,

an awesome find...an original beauty

Excellent content. It's particularly good to see stuff like this on KZfaq right now.

Great video. Thank you and hope you and your family stay safe!

Thank you for the excellent educational content during this time of isolation.

WOW!!!! That’s one I just cannot wait to see the restoration vid for! VERY COOL!

Excited to see the restoration on this!

I love your videos on electronics repairs. How about a video on saving faulty or acting -up routers.

What a cool looking radio! We have some old pioneer receivers from the 80's, but none this old or rare for sure! Can't wait to see this restoration!

Looking forward to when you get cracking with this one. I have an SM-R150, which is the same age and is just the amplifier part. There are a lot of paper-in-oil capacitors, so waiting to see your strategy with those.

Excellent project 👏👏

I love the look of symmetry on this set it's beautiful!

All precision, wire wound resisters. Very impressive.

That is gorgeous!

This series was beautiful and nicely made.

That's just gorgeous!

Very nice RX.......must look for one

Love the dual Eye Tubes, thanks for sharing...Vic

Just amazing. Those tuning eyes wow they were the best. I'm glad this thing is in the right hands.

That is the coolest receiver I have ever seen. In great condition cosmetically as well. nice job Mr. Carlson as usual.

I love vintage radios. And I'm new to your Channel. Now, I will say that my knowledge of electronics and radio repair, could be fit on the head of a pin, and still have room left over. Nevertheless, I love watching this channel and I love your videos. And I always learn something new. Learning what transistors, capacitors, and reflectors are etc. I know your doing your video's for those "in the know". But don't forget us newbie's too. And try to explain the function of these components are. Keep the video's coming Mr. Carlson.

thank you mr carlson

Always thumbs up for you Mr Carlson....your knowledge of tube circuits are second to none....

Hi, Paul. This radio was probably made just before the FCC approved FM stereo. Many receivers and tuners of the era had a separate a.m. and separate f.m. tuner. Left channel will be on the a.m., right channel would be on the FM or vice versa. And as you suppose, one of the a.m. tuners would be wider-band and the other tuner would be in narrower or standard bandwidth. Cool find!

Great project...very interesting and love your style...Thanks

Omg. When I was a child my uncles friend had this exact receiver as well as a bunch of hi-fi audio stuff from the mid- late 60's in his living room. Thank You for posting this Mr. Carlson.

Thanks, Paul! Super cool old receiver! I look forward to the restoration video.

Big thumbs up. Cool radio. Thanks for the project. The video is appreciated.

Looking forward to next time thank you Mr Carlson for recent video 60's were awesome.

beauty project!

What beautiful receiver! Very cool looking.

Great looking device, thanks for the video!

love your work. keep safe

It is a pleasure to watch your videos as I seem to learn something new each time regardless of the content. I suspect that you field this question quite often but it would be a great addition to your commentary if you could offer a story as to how you come to possess some of this equipment. Frankly, it wouldn't matter if it was the truth or fiction as such stories would simply add a touch of magic to the fabled aura of the Carlson Lab.

Amazing how beautiful designs were back then. Love these videos. So calming and relaxing.

WOW I've never seen pioneer this old💞 very very cool!!

Mr Carlson your pioneer tube reciver is cool

First, Sir, even though I only understand about 5% of what you do, I still so enjoy watching your extraordinary teaching manner. Second, as a mechanic who has restored many different machines, I am always thrilled when I can find an unmolested original condition machine. I expect you are too.

What a beautiful piece of kit. Looking forward to seeing its resurrection!

Really nice unit. I love your way to explain the layout and function. Stay safe and take care.

That receiver is a beauty. Pioneer was way ahead of it's time.

Gosh oh gee look at this beauty. How I would love this in my set up

My father was a HAM an loved stereo systems, Reel to Reel, and my childhood was filled with this awesome electronics, I remember too the smell of this components and fenol boards, solder etc.. Lovely memories.

You were the inspiration for me to get back into electronics (from my youth) and built my own lab. It has just snowballed from there. What a fantastic hobby.

God ! Could you imagine Mr Carlson refurbishing your precious receiver?

Paul: These preview videos are very interesting and I look forward to seeing these projects get restored, thanks for sharing these older projects. Although these were for sale in my younger days, and I have come to cherish my original pioneer pieces as well as radio shack test equipment.

Never have seen a Japanese valve set like this before, thank you for showing!

I love it...without words

Thank you for all these videos while I'm stuck inside with everything going on right now

Excellent receiver for a rebuild , this is exciting.

I mean... I’ve seen your leakage detector before in your other videos, but it would’ve been awesome to see what the forecast was on the one that did pass. Mainly just re-show is all “new and old” how it works. That and I love how you explain things. Keep up the great work, stay well and have yourself a great day. And thank you so much for your content.

Can't wait for this restoration

Mr Carlsons lab you are good at restoring vintage shortwave receivers and alignment of vintage shortwave receivers with ssb my friend 😅😅😅

What a nostalgic receiver.... ! Continue with the restoration, please 🙏 (Can be a 22 hours clip, if you want... we have a lot of "confined" time... 😂🤣😂 in this locked down season.... ) 👋😀

Awesome!

It's a beauty !

Very cool reciver looking forward to the restoration 👍

Really looking forward to the restoration of this unit! :D

Its very informative video thanks for your time and efforts 👍
