Incoming new amp Friedman

sherpa_man

Bought from a good friend of mine.

modded pt20

here are the mods

1. A resistor was changed out so it runs a bit cooler (it was red plating with ANY power tube that was in there, even after it was serviced by Friedman himself)

2. SAT switch added on front (based on kitchen sink mod)

3. Gain boost push/pull (located on gain control)

4. Treble boost push/pull (located on treble control)

5. slight modification in front end (not sure what was done exactly, or what the effect was, but there was a reason for it)

Apparently others have had issues with the earlier PT-20s frying the power tubes too. Friedman said to only use JJs, but it was just running so hot that it was having a negative effect on the sound. Now you can use any type of power tube (EL84) in there and its fine
