As far as the discrepancy between the Schematics and the PCB here's Papa Pass'
statement:

"As Choky sez, no issue"

So we'll now order a pile of boards which should be in the store in about a month.
I think that it's really exciting that people are trying modifications to the basic amp.

As SJ pointed out, there's more going on here: SS 120R085 Depletion Mode Jfet

Please mention it here if more threads are started or one begins to discuss the Amp Camp Amp

What would be the maximum usable supply voltage for the Amp? It looks like the 2SK170 have more ore less the complete supplyvoltage and are the limit...

I have a nice supply that deliveres close to 30V, would it be ok, provided the caps are 35V or higher and heatsink is larger...?

Despite the fact that there will be pcbs in the store, has anyone routed a one-sided pcb?

I would like to etch them myself.
