Dear comrades,
I fulfilled a dream and bought a Sunn 300T again.
A schematic from 1998 was included.
Knowing the Amp as a tube-eater, I wanted to know what was changed in the Fender Bassman 300 and printed out a 2004 schematic and compared the two.
The screen grids are significantly larger, and there have been changes in the area of bias supply.
There are also small differences in the line-out and footswitch, as well as in the area of the compressor, which I ignore at first, but the poweramp is important to me in the hope of reducing tube wear.
I attached images and highlighted the differences in the 2004 schematic.
Best, Chris

AFAIK the Fender schematic was revised at least once after the Sunn was discontinued. The few changes I noted in the output section appear to be reliability updates.
