I just picked up a TR 2080 over the weekend (free), with a couple of issues. After pulling cover I found that D919 and R955 have completely burned up. R953 and R943 show signs of overheating.
I've got service manuals for 2075 and 2075Mk II/2080. 2075 Manual has better resolution and can make out component values and voltage readings on schematics.
So I've ordered replacement parts (mouser has the BY206 diode). But I have a question about R943 and R944. According to schematics, they should be 10k ohm, but with my unit, both appear to be 5.6k ohm. Can someone confirm what they should be.
Also, with these signs of shorting/overheating, what else am I likely to find has gone south?
