stax srm-300 amp repair

hello, nah still not working.

non working -
R8 - 259mV
R7- 264mV
R8 to G = 280mV
R7 to G = 242mV

working -
R8 - 6V
R7- 6V
R8 to G = 6V
R7 to G = 6V

all 4 resistors tested measured around 60k ohms

I was also able to acquire and swap the 2SA1413 & 2sk117 transistor pairs on the non working side, no luck there either.

Have you checked the four 4.7M carbon comp resistors? The ones on mine drifted to around 7-8M
