Yes, have fun! The ACA makes a great guitar amp if you disconnect the feedback, although there is still some through P1. You should be able to clean up the high end if you double up on JFETs (Q4) and cut R9 to 470 ohms. Bigger Q1s suffer from too much gate capacitance, so stick with IRFP240's. The circuit will work fine on 24V, just readjust P1 because the output voltage doesn't track the supply.

Kits & Boards are stocked at the order fulfillment center. Listed in the store in <24hrs.
Go to "store" in the menu band at the top of the page to check every hour!

Kits have the boards included.
The drilled and tapped heatsink pair is available separately
The power supplies are available separately. One will work for 2 channels, but two make sense
if you're making, monoblocks or if you just want the cachet of External PSU's, one per channel


Or there will be a package with the kit, pair of heatsinks, and two power supplies.

Sleep is... overrated.

The Amp Camp Amp is probably slightly underrated. Makes sense. Can't wait.

Damn forum is hosted in the northern hemisphere isn't it?

I have my fingers crossed - but I'm guessing it's me that misses out.
