@@KetherWesak every MCL video is a video that I wait for. He's so good at explaining electronics. I don't really get to work on any of the vintage gear he works on and I don't think I ever will. But it makes me feel good watching a master executing his own craft at the highest level
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
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.
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!
Those transformers are made by hand in a small shop in Gaylord, KS which is on state highway 9 southwest of Smith Center. Which is odd since the company is based out of Clallam Bay, Washington.
really its the capsule where they put the money. He isn’t buying Ben’s capsule from Australia because China is more expensive. Its a $350 capsule for us DIY’ers! Assuming WA has more favorable terms. IMO the color is too much for me in the WA unless im looking for that effect, but for VO is perfectly perfect.
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!
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
Warm VP of Product Support: "Um, this TH-camr 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!!"
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!
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.
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.
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.
This video was a pleasant surprise. I asked about this a few days ago in the comments. I rarely comment in TH-cam so it kind of felt like I was being responded to. Thanks for the video.
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.
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!
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.
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!
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.
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.
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!
@@ethelryan257 LOL on sexy voice! It's not that it wouldn't make a great podcast mic, it's the price point issue. Most people won't drop a grand for a "podcast" mic, that's all.
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 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.
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.
Processing? Like audio signal processing used in broadcast? I used broadcast processing in my videos (one's that aren't direct uploads from the camera) so loudness is relatively the same throughout the video. It also allow the audio levels to be high enough that no one has to crank up the volume to hear me or the content. It's not excessively loud, but consistent.
One guess -- The big and heavy housing might be made of Mu-metal? Before I really knew better, I was wondering some audio line transformers that appeared heavy and basically like cast iron housings. About fist size overall, and 1/2" wall. When I looked inside, there was a tiny transformer, maybe 3 cubic centimeters (1/2" x 1/2" x 1/2"). We needed some more, but they were pure unobtainium. And we got an explanation that the big casing was Mu-metal for magnetic field noise rejection. Well, good to know. But we still needed something and finally settled on a more modern version, a tubular one, about 3/4" in diameter and 2" length. I never opened it or made any attempt to verify the material, but am pretty sure it also had a Mu-metal housing, just thinner wall.
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.
i have started out working on vacuum tube radios and TVs in the 60s and know nothing of Warm equipment? checked on price $950 with a JJ Slovak 5751 vacuum tube made close to the Ukraine area if so now can see why it has wonderful shock mounting... good for indirect tank canon fire 🤣better get them while you still can? 😲 tanks for the great mic info new to me 🥳
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.
Since the move, the top end seems a bit brighter - close-talk sibilance if I had to guess. But boy, that mike makes it clear why the U47 sound is loved by vocalists. In the old space it sounded positively creamy. Now I know what’s on my Christmas list. Btw who’s stand are you using? Nary a video goes by where you don’t share some hard-won knowledge. Thanks so much.
I've actually used your TH-cam 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?
Man this is a $1000 dollar microphone (with tax) I would imagine that only radio broadcasters use this equipment. Not meant for a person who is starting out on TH-cam. On the other hand, your videos are the best sounding I have heard. So the money is very well spent.
@@carlthor91 That one is cheap compared to the original Telefunken U47 that are sold north of $15,000, and the new Telefunken U47 that are still over $11,000
I love your channel and was really excited to see this one! I am a part time voiceover actor and I use the Warm-87. Best microphone ever!! I always thought Sennheiser was good until I got this microphone. Now I'll never go back! I had a question, because of the time placement is it better for it to hang upside down? I have mine sitting as I thought thats how the tube was placed. Let me know if you can and thanks again! This channel is great!
Hi Steve. I find the WA47 sounds the best (fullest) when placed in front of the face, about a foot away. The pattern is the last (Figure 8) or "Bi-directional." Thanks for your kind comment!
I was somewhat disappointed by the inner workings of the WA-47.When I was looking to purchase another LDC tube mic I chose the MXL V69M in part because it is half the price of the WA-47. However the V69 has a very substantial circuit board and after seeing the inside of the WA-47 I am even more certain I made the right choice. I would like to see a direct comparison between the WA-47 and the MXL V69M
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...
Would have liked to have had a more technical rundown on the mic. What plate voltage is used and noted the voltages on the power transformer without a voltage normally used for filament. This leads me to guess the tube filament is powered by regulated and filtered DC instead of AC commonly used in old radios and amplifiers. Dues the tube run on 6.3 Volts DC and about 220 Volts DC for the plate?

Seeing something brand new out of the box so well built and designed was actually a comforting thing to see this morning.
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
What a beautiful mic, and sounds great.
