Audio Horizons TP 2.0 Preamplifier

The only float I use(if you can call this a float) is a suggestion that Pat(Rx8man) gave a couple of years ago by using small o-ring gaskets between the screws and the Pcb. I think this is just an isolation rather than a true float. I'm not sure if Joseph is using this method or another type of isolation in his current preamp versions. I use a mix of Herbie's Feet and Isonodes under my preamp which provides for isolation and improved sonics. It's amazing how various feet can change the sound so much. I've read some good things about these Mig cones from Synergistic Research that I might try out some day. I've tried a few o-ring-type tube products that deadened the sound too much.

i'm curious, IIRC tubes 1& 3 are signal gain, but 2 & 4 are for bias. did anyone find benefit from rolling 2 & 4?

Recently I aquired a AH TP2.0. This particular one has no output transformers. Were these transformers offered as an upgrade at the time of its conception?

I am not sure but Victor, AH's representative is happy is answer all questions vcomerchero@sbcglobal.net Hope this helps
