I love the tones out of my Triaxis but hate the noise level going into my 2:90. The noise level coming out of the Record Out renders it useless. Any one have a mod to address this. Simple retubing?

I did the opamp in IC3. I put in the Burr Brown 2604. It's a warmer sound, and you don't have to worry about cliping it.

@leadfootdriver: What channels/modes are affected by IC3 change?? Please give more details.

There's been some big threads on this. It's always in the signal path. The opamp is used to drive the dynamic voice if I remember correctly. I haven't been around in a while, but managed to come up with these links.
