Default ACA with Universal Power Supply

I was considering putting my ACAs in a proper chassis and replacing the laptop power supply to supply the 19v DC. I was considering using the Universal Power Supply from the DIY store. Any advice on how to make this work? What would be the recommended transformer to use? Any modification of parts needed on the PSU to make this work?

ACA sounds great! Thanks

It's not really the right board to use... The DIY audio board is a bipolar supply, and the ACA needs a single supply.

Something like Peter Daniel's PCB would be better -- Universal Power Supply PCB

One side of his board is all you need.

A 100-200va 14 or 15v transformer, Diodes, a pair of 30,000uf 25v caps and a handful of .47ohm 3W resistors will make essentially half of a Firstwatt -style PSU.

For mono or enough for stereo?

A pair can run on a single 19V smps power supply so I'd say stereo is ok
If I'm not making noise, I'm making something to make noise

Talking with 6L6 offline - adding up the cost of a transformer, psu and chassis and - I think I will keep the Amp Camp Amp as is and build an F-5!
