For more power than is easily available from 2A3 and 300B direct-heated triodes, we offer the EL84-based Kaivalya mono amplifiers. This project began as a custom commission for an audio magazine editor. It is now a production item in our top White Range. The brief submitted for this project asked for 45-type refinement and speed, lower THD, higher linearity, more bandwidth and 25 watts of power.(...)
Our solution was a class A push/pull pentode power section with four EL84/6P14P-EV and solid-state rectification. This stage is driven from a single-ended 12AU7/ECC82 driver. Interstage coupling by our own 11-section transformer with 38 windings eliminates coupling capacitors. Between driver and power stage, we apply a very minimal 0.3dB of local negative feedback for a significant reduction in harmonic distortion (...)
