Tubelab Simple SE


A simple single-ended ultra-linear pentode power amplifier.

Assembled with JJ GZ34, ECC81, and 6L6GCs

This amplifier is built around the Tubelab Simple SE board, which is a simple single-ended power amplifier using cathode bias and commonly-available tubes. Power output ranges from 5 to 14 watts depending on the type and configuration of output tubes. It is a very versatile design and this build allows much of that flexibility to be adjusted on-the-fly.
