Was it Oliver or Max from iaudio who came up with 2 tube model to recreate the original electrical properties ?
Why a tube in the psu ?

Was it Oliver or Max from iaudio who came up with 2 tube model to recreate the original electrical properties ? Why a tube in the psu ? The D47 is based on the Ioaudio design. From what i have read and seen Max was the first to actually use 2 tube in a 47 circuit.

Cool product release.. Oliver redesign is highly respected.. Has anyone ever shot out these mics against original 47's? I am not trying to nitpick just asking? I truly hope this product is a successful for you Stam. I also hope that each and every component is built / assembled with pride paying attention to detail π oh yeah hope they ship on time as well More questions : Is this a diy kit or an actual Stam designed product? Where is the mic body head and grille made? Are they from the AMI kit? They look similar.. I do know when I looked at the AMI t47 mic kit with Blue Line and it was around $1000-$1100 and still needed to be built. Re: SA87 We are in May has anyone received their SA87 that we're shipping in March? Maybe I missed the thread? How are they sounding and comparing to other mics ( and 87's obviously π ) Has anyone used theirs to record stuff they can post? From what stam has posted i think its safe to assume that these are based on the Max's circuit and the PCBs are Dany Bouchards design. The pictures of the bodies and PSU cases show that they are from Alctron or a similar manufacturer in china. These were originally designed at groupdiy forum and close attention was made to get the head basket correct. But since then they have been more widely used. (I think the pearlman tm-47 may be the same body.) Whatever the case these bodies are pretty good quality. I have a few at home. If Stam can get a stock of quiet tubes I think these will be a good buy especially at the intro price.

I know many who have had tons of tube issues. Hopefully that's not a problem for Stam. Anyone have any experience with the Heiserman HK47 capsules?

Not even close. Not the same ballpark. The general idea is there, but in all honesty, not something I'd spend money on.

Yeah but for 10% of the price of the real deal and about a 1/4 of a Flea ballpark is pretty good! Being an M7 fan and considering most experts consider the Geniuine Neumann K47 the most consistent modern quality Capsule the choice of Capsule is what is keeping me from pulling the trigger. I know Eric is doing a very good job, but you can get the real deal and unlike the k87/67/670 they still nail it ! I did like Cowboy through Svarts clone , of course Herbie would sound good through a CB radio!

I did like Cowboy through Svarts clone , of course Herbie would sound good through a CB radio! The Flea is the closest I've heard, still not sure if drop the coin on it though. If it was me, Id get something with its own vibe. I don't see the sense in chasing something that will never be "right". It would drive me crazy every time Id use the mic. Id rather drop the coin on something like that Tube Soyez or something of that nature. I feel like the importance and beauty of the real deal mics is slightly diminished when being compared to $1,000 microphones. We have a short body Telefunken badged 47 and a chrome topped Neumann badged long body 47, both with real deal VF14's. They are astonishing examples. They blow me away anytime I use them. Put something else next to it, and it get lackluster real quick. Not saying the clones are useless, but I wish people would stop pretending and perpetuating the idea of "hey now I have a 47!". ::disclaimer:: Trying hard to not come off as a complete know it all. These are not my mics, and no I would not be able to afford them if I didnt happen to work at a facility with a beautiful mic locker for the past 10 years. The opportunity I've had to use so many badass mics has left me slightly jaded when it comes to the clone market is all.

I bought some spares from the british distributor, but I've not put them in yet because the two that Dan finally ended up with are good.

I assume the K47 Classic capsule offered by AMI and the BV08? Thanks

Good luck sorting through all those tubes to find quiet ones. I can think of a few things I'd much rather do than try to offer this configuration as a product. Pulling all my teeth comes to mind.
Even when you think you've found a pair that are quiet after 50 hours of burn-in time, they will spit and sputter on you randomly when you go to use it in a session. And yes, I've tried all the variations, including the expensive gold Phillips ones from England.
Best of luck.

I had multiple important sessions that it ruined. Luckily Dan (with your help I believe) found tubes the work and replaced a resistor, and it's been fairly reliable since. I know both you guys have had "issues" (that's putting it nicely) with all variations of these tubes...... I count myself blessed that mine works so well...

I have one built and then torn apart along with parts to do another. When I get time, I will use a different tube. There can't be enough supply of quiet tubes to supply all the kits and now product of this mic. Dan and I went through piles of tubes to get the 2 that were quiet enough to use in your mic. I finally found 2 for myself only to have them crap out on me during a session.

I bought 4 "matched" tubes from England just in case I ever have mine go out in a session, but at that point, I'll probably trash it. Until then, it sounds great! Good luck with yours. I'm not sure how Max ever thought these would be "trouble" free....

I think Dan got his going. We certainly had a lot of trouble with those tubes. I did the matched ones from England as well and still had trouble. They sound great when working, but were too unreliable for me. Also, the noise floor was too high for anything critical.

Sorry to hear of your troubles, this is exactly what I don't want to deal with.. Was this is the same build or circuit configuration you are discussing ( two tube setup ?) Which capsule did you go with ? Have you heard a Heiserman capsule by chance? Anyone re: Heiserman capsule? If these capsules are so great why do I only hear about them employed in DIY/ cloning? Any links to comparison audio files against similar capsule or even a different capsule and build just to get a ball park ? ( heiserman 47 cap vs kk47 for ex )

Any links to comparison audio files against similar capsule or even a different capsule and build just to get a ball park ? ( heiserman 47 cap vs kk47 for ex ) It was the Max MK47 kit. Same dual 408 tube config. Between Dan and I, we had 3 different capsules on 3 different mics Thiersch blue line and red line M7, and a Beezneez M7. They all sounded really good. The Thiersch caps were better. The PVC membrane was the best overall, can't remember if that's the blue or red now? Capsules did not contribute any noise as I did tests without the capsules using a 47pf capacitor in place of the capsule to listen to just the amplifier. Those tubes are a nightmare. I have not used or heard the Heiserman capsule.

Isn't that why we have Bowie aroundπ But seriously that's the biggest problem with most modern non- original circuit clones, Tubes that can do the job vs designed to do the job and finding those that are up to the task! Dan built mine, and he went thru dozens of tubes to find ones that were even mediocre. It complicates testing and verifying that you need two good ones. The good news is, they are in no short supply. I bought some spares from the british distributor, but I've not put them in yet because the two that Dan finally ended up with are good. I have well over 100 tubes here that I had to test in order to find a few pairs of tubes worth putting in mics for the few guys I built them for. I had to build a tube tester specifically for this purpose. Then you have to burn them in for 24 - 50 hrs then test again. I rated the noise floor and the random bacon and eggs frying sound for each tube! Finding pairs that would work well was not a simple task. I stopped building them after that. I have a pair that work great now and I have a few spares tubes for when these go bad. I would design around another tube for any future builds. BTW, I got about 10 or 20 tubes from Bowie for these and I couldn't use any of them. It wasn't Bowies issue at all. He told me in advance that he didn't have a way to test them. I pressed him to find me some and I took the risk even when he wasn't excited about it. I only say this to say, it can be problematic for a tube guru like Bowie to find some of these that are worthy of putting in a mic. My 2 cents

sll Thiersch Blue line is the pvc membrane based capsule and the red line is Mylar... again thank you for the concise info, very appreciated, $1100 is no small coin for me. Let alone to pay that much for headaches and troubleshooting... I am not as skilled as most regarding DIY so paying a tech would also be an expense of mine for this situation and something I had not thought of til now... This thread and a few others have made me appreciate the miktek cv4 even more... dandeurlooWow even more great info.. man I really love this place ππ Bowie doesn't test the tubes he sales or he wasn't able to test this particular tube for this circuit ? I have heard Bowie is the gold standard tube guru π So for him to have trouble speaks to this tube...
