I bought the Model 1 amp a while back to match my PS Audio 5 preamp, thinking I was going to either fix it or gut it to install a JLH for ESL amp module in it...The amp works, but needs a complete recap - lost interest in doing it myself and other project are taking up all my time.
The PS Audio 5 Preamp is a great SS preamp with an equally impressive phono stage. The amp was modified by a previous owner and cannot identify what he exactly did. All I know is I purchased from a subsequent owner that indicated it "made his amp go crazy" when set as an active preamp, so he used the Straight-wire (passive) setting for years. After looking at it I realized it is a direct coupled preamp (no output caps) and had a full dc volts on output. From discussions here on DIYAudio, it was recommended that I put 10uf output caps in to work with any amp someone may connect. The 10uf caps are from my Magnepans - and are Rel-Caps.
Anyway, the preamp makes a nasty thump when switching from Straight-wire (passive) to active, but otherwise quiet and sounds great. And also a great SS phono stage...comes with the original separate power transformer too.
Pics to be posted shortly
