Aleksi’s 2-channel amp

Aleksi’s a very serial amp builder, and a regular over at This is his scratch-built 2-channel push-pull amp. It uses a modified Amp Maker chassis and is stuffed with turret boards. Aleksi is using the super-easy to work with PTFE (teflon) boards for sub-assemblies all around the amp.

“Just wanted to send you a few shots of the work in progress. I’ve managed to get the first sounds out of the amp, the first preamp channel and the output stage (along with VVR) are working OK.”

The second channel includes one of Aleksi’s favourite circuits: a parallel 12AX7 driving an EF86.
