How can I tell what version my Triaxis is?

I just picked up a Triaxis in a trade. After many many years of wanting one, I'm simply not into rack gear anymore......go figure!

Serial number is: T-7688
Board Rev is: TX3

Not sure if I'll keep it, but it has some sick gain for sure.
Any help identifying this version would be greatly appreciated.

When you turn on the Triaxis a number appears in all of the display windows. That's the version.

According to that and the srl# you mentioned you should have a FAT/PHAT mod V2 Triaxis....
Check for the TX4 board on the upper/back left (when looking from above/front).
If you don´t like how Ld1Red (Phat Recto) sounds, check this thread (reverse Phat to Non-Phat):

Also, swap IC3 (OpAmp in DV-circuit, stock TL072) for an OPA2604...big improvement!

Right on, thanks guys!
The board does indeed say "TX4 D."

The only thing wrong with it is the LED for LD1 yellow does not work.
Which version is more sought after?

Where is IC3 located? I took a bunch of pictures, but can't find it. Maybe I'll have to open it back up this afternoon.

Just took the TX5 pic as reference; IC3 is in the same location in TX4 Trixes as well ;-)

IC3 is on the back main board just to the right of the TX board.....
There's a bunch of schematics, service docs and disassembly instructions on http://www.tubefreak.com
But then, you're the amp-tech

Subjective with which version is more sought after..... I guess the V2 non-phat is the one
