First Project - SE 6V6

Post by GarageGeek »

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.
