In Reply to: Biasing/tube changing... Stax Tube Driver Amps posted by GreatSound on June 27, 2021 at 11:47:59:
The best thing you can do to improve the quality of the Stax tube output amps is to substitute a constant current loads for the plate resistors. All the Stax solid state output amps have constant current loads, which is the reason that they have a significantly higher maximum output than any of their tube output amps. The plate resistors burn/waste more than half of the signal current generated by the output tubes.
