are those bigger resistors connected to the plate terminal of the preamp tubes?
I have fixed an old hybrid Shengya amplifier VL-250, those resistors from HV B+ to plate terminal burned also.
its value is 6.5K-ohms together with the bleeder resistor 220 K-ohms.
if not, you may still need to trace the circuit.
Good luck dude!
