Power Supply Capacitor Board with *EFB™

Perhaps the most significant upgrade available for the ST-35
Our new power supply / capacitor board with EFB™ converts your ST-35 from cathode bias to a new and innovative "Enhanced Fixed Bias" mode.

Benefits of EFB™ include:

Increased output power (both channels driven)
Lower distortion
Lower bias current for extended tube life
Much more than just a replacement for the original twist-lock cans, our capacitor EFB™ board also replaces all the resistors and rectifier diodes associated with the power supply. Features significantly larger overall capacitance and 105℃ rated components far exceed the originals in quality and reliability.
