1612 Tubes for vari-mu compressor

So I was so interested in the 1612 Tubes I got to play with... I started a hybrid design. The concept is a vari-mu style compressor using the 1612 as the front end after a Jensen XFMR. I am thinking of then running LA2 style buffer and driver amplifier into a Jensen output XFMR. But the side chain will be solid state and use either a LOG amp or a THAT audio engine.. Sort of a complex blend of 50's tech with more modern tech...
The panel below is the feature set that I would want...I interested to hear your thoughts or wants for a compressor like this...

Changing Tubes - ART Tubeopto 8


Ive read a few threads about changing the tubes on the ART Tubeopto 8. I got my hands on some vintage telefunken ecc83 smooth plates and I can’t wait to hear how these sound! Several of the threads I’ve found note that you need to remove the tube snubbers before you pull out the tubes and replace them after.

I’ve only ever changed tubes on amps where there are no snubbers involved. They seem pretty glued in. I was wondering if any of you have experience with this, and if so how you got the things out?

Changing tubes on UA LA-610 - worth it ?

This video shows the process of changing tubes and comparing the before and after sound. I've did the mistake of recording with low gain to get the cleanest sound possible, before and after.. but it seems the sound is very similar but gets different with higher gain settings.. Anyway I hope it will be of interest to you nonetheless !

Let me know what you think !

AKG Mic /Telefunken Tube

Here's a song I recently did where I used an AKG SolidTube mic, replacing the stock 12ax7 tube with a Telefunken ECC83-TK.

I've been using a 12AT7 for a few months, and I've been wanting to try a Telefunken tube.

Cover version of a Warren Zevon song; Accidentally Like A Martyr from his 1978 Asylum LP Excitable Boy.

NOT A MIX. LOL - NOT EVEN A ROUGH MIX. Just to listen and talk about the mic/tube. Here it is:

AKG SolidTube problem - solved!

Several months ago, I had a conversation with Bos about a mic I own - the AKG Solidtube, and how it was making some noise after it heated up.

The noise was similar to what you would hear if you took a tissue or a paper towel in your hand and scrunched it.

Yesterday, I dug the mic out again, thinking I'd pop the top on the power supply to see if there were any obvious indicators - like blown caps, etc...

AC701 tubes for Neumann, Schoeps, etc. mics

Just got off the phone with Eurotubes (http://www.eurotube…"]Eurotubes - Vacuum Tubes by JJ Electronic - ECC83, 12AX7, 6L6. 6L6GC, EL84, EL34, KT77, KT66, KT88[/]="http://www.eurotube…"]Eurotubes - Vacuum Tubes by JJ Electronic - ECC83, 12AX7, 6L6. 6L6GC, EL84, EL34, KT77, KT66, KT88[/]). Seems like us Neumann, Schoeps, AKG, etc.

LA-2A Tubes

I have two band new UA LA-2A, bought two sets of GE LP 12AX7 pair + RCA 12BH7, that were vintage new and matched and switched the stock LA-2A tubes out.

Was there a difference?

I used a Neumann M 149 into an SPL Premium mic preamp (which conveniently has two outputs per channel, (a cool parallel setup).

Help! Groove Tubes 6TM Power Supply cable Pin out schematic/ ADAT Elco to 1/4" snaKes

I have an old Groove Tubes 6TM mic with the PS1 Vacuum tube power supply. The mic end looks like the Groove Tubes EC7 cable in that it has a 7-pin connector. The power supply end looks like an 9-pin ADAT sync connector almost like a vga computer display connector. I am in need of the pin out configuration so that I can build one or a source to purchase one. Also does anyone have any ADAT 56-pin Elco to 1/4" snakes. I am in need of at least 2 and as many as 4. No luck from ebay or the usual suspects.
Thank you
