Default Counterpoint SA-1 preamp schematics?

Hi folks,

I have a Counterpoint SA-1 preamp for years. Bought it used and mostly used it as a linestage. Pretty transparent and nicely matches my Sugden AU-31 when I feel like using sandzistors instead of the 300B.

Since the fan was noisy I dismantled it and cleaned it (gee.. lots of dust inthere..) to find out that two resistors are burnt. Probably in the phono section because as a linestage it was ok, and I didn't use my turntable recently.

So, since these resistors turned black I have no way to guesstimate them, and as well, I wonder why these resistors had problems. Why they became so hot.

If anyone can refer to a schematic, I'd apreciate.
