Audio Horizons TP 2.0 Preamplifier

I was wondering if anyone received an owner's manual with their AH preamp( any version). I don't recall getting one and was lately wishing that there was one. I would like to get a schematic of my TP 2.0 to look it over. I haven't talked with Joseph or Victor yet...I thought I'd get current owner's comments first. I didn't see one available on their web site to download.

Sherod,

I have a rudimentary users manual when my unit was a 2.0 but no schematic in that info. Another omission in the early manuals is the fact that the preamp inverts polarity. Make sure all who use this preamp switch positive and negative speaker cables EITHER at the amp end or speaker end (not both) to get the correct phasing.

Sherod,

Thanks very much for all the details.

Scifi,

Thanks for all this information.

Sherod and Scifi,

I have contacted Joseph Chow about the tubed power supply grade. I will report back here -- hoping to have a positive outcome soon.
