I'm sure a man of your calibre would soon see why it doesn't perform.

There is also a pre-set brill pot on the small t/base panel at the bottom of the set, RV405. Try adjusting it, if the A1 volts are low there is a 220k resistor and a 0.01mfd cap on the small pcb inside the eht tower. Suspect these, Malc.
