just a write-up I did last year on my upgrading of the Dynaco PAT-4
6th Street Bridge: Upgrading the Dynaco PAT-4 preamplifier
with mods for bypassing one of the output caps, tone controls, etc. Again, the end result isn't world-class, but for a fun project or something for a beginner DIY-er, the work is easy.

This mod disables the tone controls and lowers the gain, reducing the hum and noise by around 11 dB.
