I lost my psi and have been trying to find a replacement now the pedal requires 9vac 1.3 amps my question is how picky is a pedal like this? I have a psu that gives1.5 amps will it harm the pedal at all? Thanks

Hey~
I've been reading all of your posts on the SSamp forum. I have 3 RG100HT .
All of them have really crappy volume drop when the treble is pulled (gain
boost). I looked at your 3 page schematic but can't for the life of me figure
out what part specifically I can use to get the volume back up when the
treble knob is pulled.
Can you point me in the right direction?
Thanks!
jason

I made that amp a few years ago and it's awesome.
Here are my samples:

1.Yes the red channel is the distortion channel
2.Caps are in micro farads (10uF on the source of Q6)
3.Yes they are 4V Zener diodes,(1N914 are clipping diodes,or boost in that amp, but they attenuate the signal a lot).
