Hi, I need the value of the resistor that feeds the 145V to the emitter of TV06
(BD680A). TV06 is bolted on the same heatsink as the line output transistor. From board marking it could be rd38 or rd 28, half of the number is under another component

TIA
Richard

Thanks Ray,
I've already downloaded everything listed but it only gives cct
diagram for the power supply.
I did however find a reference in the fault tips to the value 2R2.
Whats really needed is the cct diagram for the line output stage, damage was done with the B+ line at 180V. The supply is now sorted and at 145V, but is
being pulled down and tripped when TV06 is connected to RV38,
Ideas ???
Thanks
Richard
