messing around with this chassis, checked Q302 and Q303 just replaced anyway, checked resistor r313, within spec.recapped chassis. checked continuty on the yoke wires to all their points. replaced IC. 301. checked all the resistors and diodes in vertical section in circuit, had a working 4900 to compare. ohmed out all vertical pots in circuit and seem to be ok. TP82 is giving me 55vdc . on my working chassis I am getting 32vdc at tp82. also the heat sinks on Q302 and Q303 the pads that are anchoring them down are completely burned off but dont seem to be electronicly connected to anything. any suggestions?
