Sharing my first ever tube amp build. This is essentially a clone of the Marblewood design from Cascade Tubes at https://www.cascadetubes.com/the-6v6-marblewood-amp/
This is a SE design using a 12AU7 or 12AX7 to drive a pair of 6V6S power tubes in UL mode. It makes ~2.5W/channel with ~2.5% THD. I've set it up with a pair of Klipsch R-41M speakers (90dB) and rarely need over 1W for full enjoyment. At that level the THD is closer to ~1%. This amp is also absolutely dead quiet when it should be.
Many thanks to the many internet resources that guided me. I'm very pleased with my first project.
Very nice. I have some 6V6 tubes now, might need to build one of these :) Looking at the schematic, looks like a nice design. I can't help but want to toss a Schade feedback resistor in it :P
You couldn’t have asked for a better outcome. You’re amp looks very nice.
Looks super. Like it!
