Speaking as a sound engineer, I will admit that Mr. Carlson does an excellent job with his audio. Five star rating from me.

I’ve always thought you have the best voice audio of any channel I watch.

I love the sound from that microphone! Always good sound on Mr Carlson's Lab videos.

Of course every piece of gear is modified! We expect nothing less. It's just part of why we love you, and can't wait for new videos! 73 de KB3HUC

Dear Mr Carlsons, I'm new to electronics in new very little. I bought a few electronics, solder iron oscilloscope etc. In the past few years that I've watched you I've learned a lot, but in comparison to most people I don't know squat. But if I was to say out of all the videos I've seen you would be the best teacher I've ever seen in my life. The way you explain things, they trace down a problem even a dummy like me understands it. Thank you for your videos I truly do appreciate it Joe

You should build a tube compressor! Like a fairchild 660!!! Would love to see that!!!! Or even a restoration of one!!!

I've commented to the wife in the past that you have the best quality audio on KZfaq. I now know why :)

Microphone sounds very nice. Cozy and warm, like a tube in a sweater on the fireplace mantle during a starry winter's night...

Warm VP of Product Support: "Um, this KZfaqr modified his microphone, should we void his warranty?" Warm Chief Engineer: "Are you kidding, that's Mr. Carlson, get him on the phone & ask how much he wants for his schematics!!"

As someone who has moderate to high hearing loss I have to say I have always appreciated the excellent audio quality here. (And that the closed captioning is always good too.) I know not all creators can afford this kind of gear, and I certainly don't hold that against them, but I do appreciate the extra effort that goes into these videos.

The transformer (by AMI) is very nice-clearly where they spent their money in this product. 5751 is a very interesting choice for a mic modeled after a U47. If you’re curious, try modifying the circuit to use an EF800 or EF802 instead-since you have two, it’d be interesting to get your thoughts on the comparison!

The very first thing I noticed about your channel was how “warm “your microphone sounded. I recently bought the same microphone for an audiobook project and just love it. I look forward to the video of your modifications and would be seriously interested to hear a comparison of before and after mod.

I love all the valve/tube stuff, Mr Carlson, keep it coming!

I'm looking forward to seeing the processing gear, this video was fantastic as well. Good job, Mr. Carlson!

I’ve not seen a tube mic before.it looks and sounds quality

A warm thank you from the UK 🇬🇧 love your videos !!!

I finally understand why your videos have that unique tubey sound. Thanks for sharing!

Nicely made mic , interesting differences to the original u47 . Last year I fixed one that came out of Olympic studios in the 1960's.

Thanks for making a video about the mike. I've asked about it before and now that smooth, clear en warm sound is explained. This is a great video about an excellent microphone. Cheers from Holland!

Been watching for a long time, always wanted to see a video about your microphone. Just had to press "like" before the video started 😁💪💯

Hope Warm Audio wíll notice your warm words about the WA-47 and credit you. To hear it from you should make them very, very proud about their mic. Thanks so much and can´t wait for the processing gear, hope you have a tube comnpressor and you will show us your modifications and how the electronics work. Brgds

This is cool, I honestly thought you were using a repurposed vintage mic. I didn't know they still made mics like that! that's just awesome

wow i didn't expect them to give a really nice box to store it in as well it really nice mic and yes i can be positive Mr. Carlson

Seeing something brand new out of the box so well built and designed was actually a comforting thing to see this morning.

Thank you Paul for sharing. The mic indeed sounds fabulous. Of course it has got some extra sauce added, Carlson style :). Much love from germany, my friend.

i had been wondering about this for a while, thanks!

I've always been impressed with your audio quality - now I know why. Thanks..

I was looking at reviews on Amazon. Everyone raves about the sound quality. The only complaints were failures that seem to be related to damage in shipping. Tube failure most common. I can just imagine these delicate things being abused no end by shippers.

The foam used to hold the mic looks very similar to hvac foam insulation tape, it stands up well to hot/cold temperature fluctuations. I've used it before in some older CB radios where the factory foam had just disintegrated over time.

Very nice mic indeed. Sound quality is amazing on these. Have not seen many clone knock offs yet. Thanks for showing details paul. I was just doing a mic preview on Patreon last week. Doing a little experimenting myself.

That's the secret behind the relaxing and pleasant voice that teach us the art of electronics. State of the art equipment improved only to get closer to perfection.

I now understand why you sound so great on your vids! Not in my budget for now but wow, nicely built!

Yay! I knew you'd get around to this sometime!

I guess this review proves the microphone's quality and ability to reject interference, based on what must be a pretty high interference area. Great demo.

I find it kinda cool that there is some equipment still made with tubes.

That IS a GR8 mic! It is so quiet that it would be a full waste to use as a podcast mic! It does have a unique "warm" sound that so many people comment about. Of course! That vacuum tube sound! LOL. I was expecting it to price out well over the $1,000 mark (US) too. I wonder how it handles other sounds/music, and the like. I'd LOVE to record a large church organ with it. That large area condenser seems capable of reproducing those low notes. I know it likes bass, because when I watch your vids, I attenuate my bass waaay down. I'm sure my system is mostly to blame for the heavy vocal bass, and not the mic. Fantastic!

Without being a sound engineer you can tell by the sound that this is a very good microphone and I always enjoy listening to you speaking. One thing that would be interesting to know is how the switching of the pattern works.

Huh, so this is why your audio sounds so good on your channel! Cleanest audio on KZfaq! Very nice!

Thanks for the video!

It has that warm sound that tube amps are so well known for

another video to watch, great man

Work of art

This video was a pleasant surprise. I asked about this a few days ago in the comments. I rarely comment in KZfaq so it kind of felt like I was being responded to. Thanks for the video.

Gosh, that looks expensive! I always knew you had a microphone of exceptional quality, because just the way the sound of your videos come out is outstanding. Even playing back on crappy speakers, like on my iPad your videos ‘sound’ expensive!

I have always found it fascinating that despite all the back and forth discussions, the best mics are tube based.

I enjoy a nice box too. And it's tight and soft as well?!? I think im jealous of your new play-box Carlson. It has all the features i look for in a box... Take care of her bud!

Another great video and interesting to hear why your channel has very clean audio.

I’ve never heard about such a thing! This is so cool☺️

Paul, I don't know anything about audio/video things. What I do know is that your videos have the best audio I have ever heard.

Superb Audio Quality !!!

Excellent sounding microphone. It compliments your voice nicely.

Nice video. I changed my tube mics to 6DJ8 tubes and I prefer them. Mine are ex Tektronix tubes, when I run out of them I will try the JJ 5751. Your audio is very nice.

As always Great stuff!

I always wondered what you were using, Paul. Now we know.

Oh that's simply awesome

Only Microphone I ever had was a Shure I bought from Radio Shack in the 1990's. I used it at a local AM radio station when I was part of a talk radio program.

9:14 you mean there is the treasure inside 💯

If you could find an original Neuman U47 you would really love that mic. The only issue with them is if the VF14 tube was "borrowed" it is almost impossible to replace for less than the price of a car!

What a beautiful mic, and sounds great.

No Wonder you sound so good, there is a tube preamp in it, the best there is! Loved this video.

Another great video

A true thing of beauty!

That $1,000 mic sure sounds good through my laptops 1" cheap Chinese plastic coned speakers, with 500mW of peak power 😂😉

I Shure didn't expect the inside to look like that !

I don't comment enough.....but I love this vid and more of the shorter ones shango style. What I mean by that is the first diagnose, then go about the restoration if needed ir wanted......you learn so much more. And this vid, I've been meaning to upgrade my mic/mixer I use in talking on radio......this is wonderful and helps me in making a decision before dropping money down on all the cheaper crap on the market. You sound great and looking forward to more.

Treading carefully here...as far as clone U47s go, the WA47 is the one of the cheapest. It's so well priced, you can afford to have 2! This is definitely not the case with a Flea, Wunder, Beesneez, or Heiserman, but then again, I think you would be very enthusiastic indeed about the build quality and components of these clones.

nice video paul''''''im glad you touched this subject because soon i have to set up a ''video & audio setup like yours for my ''laboratory' 'maybe someday you will discus ''web camera's''''''''right now here in oklahoma we are in a ice storm'''''''73's.'''''''james.

love seeing things made in the USA

WARM makes excellent gear. I'm always a sucker for a 5751, def awesome to see one used in a condenser. I have a couple of old JAN GE 5751's that are my go-to for V1 in 12ax7 type preamps.

It's happening! Oh man I love mics

I always wondered what mic you use, I've always said you have the best audio of any channel. I'm going to buy it.

I love my JJ tubes, using a quad of kt88s in my daily amp

Waiting for the mod thanks for posting great review.

Having the best sound on YT internet ain't easy...

Mic sounds great!

Whenever I watch your videos, they just inspire me to go on and on with Electronics. When you mentioned about how much you modify devices, it doesn't surprise me, I even thought it before you said it. Keep going. I'm sorry that I stopped supporting your Patreon channel. I'm currently on benefits, but when I'm better off financially, I will surely support your channel, all the best. Paul.C United Kingdom.

I think a lot of people might be surprised to learn vacuum tubes are still in production. I've known this for a very long time.

No wonder why you sound so good. Fantastic microphone that is so well build it should be a crime! LOL

Wow that's a quality mic Paul, I had no idea something like that was available. Slightly above my price point though, I'll have to stick to my Yeti 🙄🙂

Awesome stuff. Use their 1176 and Pultec style eq.

Oh my! I was hoping for a video focusing on The Microphone!

The secret to Mr. Carlson's warm audio, is indeed Warm Audio! The ending with the twirl instead of the negative image was kind of creepy with the way your face twisted up.

A very nice sounding microphone in your videos. Apparently made with a Rode capsule.. Another good brand (and from Australia!). Impressive build quality and price for a '47 mic. Might be overkill on the Hallicrafters HT-44, but maybe not...

Looking forward to seeing your modifications to this microphone!

nice Job again MR.C

wow very nice

finally! thx!

I totally understand the price after seeing the parts and workmanship!

When my toastmaster club went to in person meetings with a zoom option I learned how much the computer techs do not know about mics and audio, they think that a cheap omni directional Mic for phone conversation is better than a boom or quality directional heil Mic. It would blow there mind and argue that a very high quality Mic that has a vacuum cannot be be better that their cpos pick Mic and speaker. Great video Mr. C.

Mr Carlsons lab your new tube microphone is cool

Mr. C. Thank You ! .....Do you use any sound absorbing material in your video recording room ?...Maybe it's just me. But your audio is coming through so crisp and clear...Any how. Thank you again for taking the time to put these video's together ..... Rick. Canonsburg, PA.

I've actually used your KZfaq videos to test the output stages of various audio systems -- that mic, and your wizardry around it, are an unbelievable combo. If your video sounds like crap, I _KNOW_ I have a problem. 😁 Most people I've known in electronic engineering are fairly haphazard with audio, so this is clearly no accident. How'd you end up venturing down the audio road?

I would love to know your mods. Thank you. I’ve learned so much about electronics from you.

The Science on the foam tape in the microphone mount.... Any thermoplastic will creep under sustained compression or tension. Whoever spec'd the mount foam was likely a EE! Crosslinked polymers, like actual rubber does not creep. Actual foamed rubbers are pretty expensive (Nokian snow/ice tires are an example) Most likely the tape used was made of ethylene vinyl acetate material. This material is used in shoe soles and is known to creep at least 50%

Nice mike, littlw question would you use that mike with your ham gear? (with adaptation of course

Ok so NOWWWW I know why your channel has such a smooth sound. Unlike most channels that cause high frequency ear bleeds. LOL

Nice Mic! I would love to see an old Telefunken, AKG of the 1920-1950 area. Here in Germany those where great Microphone’s. Or a old reworked Shure.

"Tonight on Mr. Carlson's Smooth Jazz Hour"...

As always, very nice video. Quick question. How would this condenser mic work on an amateur radio station?
