Thanks but the credit for that idea goes to another member here in the ground.

So...
Finally got all parts to finish (or try to) this conundrum
After replacing all damaged parts and checking all associated components I power it up (with bulb on the plug) and up we go.
Setting up idle and offset let it sit 5 minutes (service manual instructions) and no problems so far...
Next I plugged the test lead and speakers and there was sound but, left (original faulty channel) is slightly lower then the right one, no distortion I can ear going to get the oscilloscope from storage and check sine/square ware for level and distortion.
One last thing the bulb is always with a very small glow (60W bulb) enough to make me scare of powering it up direct from the mains.
Any suggestions ?

Measure the mains voltage presented to the amp--- then you'll know how much drop is being absorbed by the bulb. If you're still nervous about moving to full voltage, install a higher wattage bulb. Bulb will be even dimmer, applied voltage higher still.
