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..

Hi!

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.

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 !

Hi there,

I'm starting to check for a place I can thrust to buy tube kits for my 2 x LA-610.
Affordable and good sounding (dreaming here ;))
They are both mk1 and were buildt around the same year but actually don't sound the same.
I guess they have different tubes or different wear on them.

Any suggestions ?

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.

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.

Not sure if this counts as pro gear, but it seemed the most appropriate forum.

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.

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 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.
