I was lucky enough to buy 1500 of these EF800's that I have been able to fit into the SA-47's from a local tube guru in Chile. He actually had hundreds of them stored in his garage, I could not believe my luck. Tubes make a huge difference.
I recently bought the last available batch of 500 Telefunken EF800's to fit into the current SA-47 MK2 and leave spares for repairs for some years to come. Other than this I am pretty sure it will be extremely hard to find more in numbers but for every problem there is a solution and where there is a will there is a way.
Your voices sounds great man!

Hi Did anyone do any further tube experiments? What does the Russian valve sound like? I'm in the process of buying some tubes for an experiment. I noticed when comparing the audio files v the Bluebird's U47 - heisermanaudio.com/products/h47tube - that static eq could not turn the H47T into the Blackbird one, but using a multiband compressor as eq I could manipulate the sound to get loads of great sonic options - I wonder if I will be able to replicate tube swaps with multiband compressor eq. Anyway, thanks for the great posts!

Think I remember Dave saying they tune the capsule to the tube, so it would be off if you put in another tube…but don’t quote me on that.

I personally wouldn’t touch my Heiserman’s tube at this point, unless it had a problem…only because I’m super happy with it and it was, as far as I understand, tuned to the circuit/capsule (as others have said).
I’ve found multiband compression to be a very powerful tonal tool but less is definitely more to my ears: the natural sound of the right mic with right voice (in right room/location) is hard to surpass.
If you want another tonal option you might consider buying the alternative capsule for the mic, if you haven’t already (M7 vs k47): for me, both are keepers. It’s a bit more expensive than a tube though, only drawback

47/48s can be dicey to fit into a busy modern mix in my estimation. Lots of low end info to deal with.

This is my next mic for sure! 3-4 months lead time apparently

John these sound really great and the VCOMP and your voice do something nice together. But how could you not finish the phrase!?!?! You're killin' me man!

Hi, thanks for replies
I reckon I can approximate the M7 capsule with a multiband compressor - I have a nice VST compressor that remains very transparent.
Every mic and guitar amp I have ever bought comes with a warning to stick with the tube supplied, in reality changing the tube can sometimes give an amp or mic a more "desirable" response.
I have bought a couple of Siemens ef184's and will buy a couple of the Russian tubes that were mentioned, and maybe a Phillips. I also have a Telefunken EF800, so hope to experiment in a couple of weeks - I'm in the middle of redoing my studio acoustics.
I have done a decent amount of tinkering with changing tubes in the V1 position of a valve amp, I hope to get similar great results with the mic. This is quite an interesting video and it shows you how much you can manipulate the response with a simple valve change:
I have a Rode NTV, which always had an annoying tonality, after pulling out the tube I noticed it was a cheap one which explained why the sound was not as good as the other components would suggest. After a tube swap it sounds great.
I have a certain amount of sympathy for the microphone manufacturers because it is hard to get hold of a large number of the most sought after tubes such as Telefunkens.
I think it is important to make the point I am not unsatisfied with the current mic tonality - I think it will be interesting and useful to do a bit of tinkering to see if it can be easily changed to take on similar characteristics of other great mics, or to create some useful mix friendly coloration.

Hi, thanks for replies I reckon I can approximate the M7 capsule with a multiband compressor. Welcome! But approximate an M7 with a multi band? Surely you jest. Of course, I guess proximity is called for here. Same city? Doubtful. Same state? Possible, but not likely. Same country. Maybe....feeling lucky? Same hemisphere? Yeah, you can probably get that close. ![:D](//storage.proboards.com/forum/images/smiley/grin.png) A quality M7 like the 70's to mid 90's Gefell line (classic design still built to 1940's standards at that point, but modern enough to not be falling apart) were / are some of the most insane mic capsules ever made. At the top of my personal favorite list. Once you grab the sound waves and transduce them with something other than a legit M7, there is really no substitute to regain what a real M7 does. I'd hazard to guess that ericn might agree. Eric? ![:)](//storage.proboards.com/forum/images/smiley/smiley.png)

You might mimic the dynamic characteristics of an M7 but there is far more to it than that, distortion characteristics and off axis response to name a few. Even wheel it comes to the dynamic s your going to find that the amount of compression is going to very with SPL a lot of these micro dynamics make the difference.

I'm sure you can also land a 747 without any training.

I had to land a 747 years ago, when the Pilots were both knocked out! (Freak lightning bolt-not the usual) Anyway... I managed somehow not to totally crash it upon landing. But it still went "Boeing" anyway. ![:)](//storage.proboards.com/forum/images/smiley/smiley.png) Chris

Of course it is not going to be exactly the same, for a long list of reasons - hence the word 'approximate'.
And I was clearly talking about swapping capsules on a Heiserman.
How about someone with both capsules makes available 2 suitable vocal files so I can attempt my crash landing?

It should have auto pilot, but it is a Boeing so auto crash?

Didn’t Boeing try to do a series of musical advertising with the “Doors”? They never were able to make it happen though as one of them went missing!!!!!
“My best Boeing attempt for Chris”

Did everyone with both capsules eat the fish?

If someone has met me yet, and about to meet me in person... I tell them I'm approximately Brad Pitt and Johnny Depp, rolled into one. And once I lose half my roll. I'll be tall enough for my weight. ![;)](//storage.proboards.com/forum/images/smiley/wink.png) Chris
