I've had this amp for about five years but have mostly used it as a back-up amp for the past two or so years. Specs and marketing spiel are available
here. I modded it soon after purchase, which really helped improve the amp. The mods include:
Blackgate N caps in the siganl path
Blackgate and Rubycon ZL caps in the power supply
HEXFRED diode bridge
Kimber 8TC speaker wire.
About a year after I purchased the amp, a pair of the output FETs blew in the left channel, and I had to replace them and a number of other parts. Since that time, the right channel has emitted a low-level, high-pitch squeal for the first few minutes after the amp is plugged in. This noise does not re-occur after the amp has been plugged in for a little while. If you plug it in and just let is sit powered off for a while, it will not make the noise. Oddly,
other people have reported the same noise in HCAs. Paul McGowan didn't seem concerned about it, so I haven't tried too hard to fix it.
The top of the case has a few scuffs and light scratches, but the amp is in otherwise excellent cosmetic condition (see pictures below and in my gallery).
Considering the condition and finicky nature of the amp, I'm only asking
$500 $450 shipped. Accepting offers.
