Well i hooked up the eht to the crt and moved the whole lot to one side,heres
a few readings i took,on q387 base i get 8.8v,it should be 2.6!,r290 wiper
measures as follows,fully cw=3.44,fully ccw 3.4v,r190 is fully cw3.4,fully ccw
3.4v,dont know if this helps?

Base voltage at Q387 doesn't point to a failure by itself. We need voltages at other nodes to tell which component failed. This was the list in the earlier message:

Voltage at bases of Q350, Q360, Q376, Q386
Voltage at collectors of Q377, Q387
Voltage at the bases of Q370, Q380
Voltage at the collectors of Q370, Q380

R290 and R190 voltages look fine if you are measuring voltage at the wiper (center) terminal.
