Default TS-530s Finals neutralization

Sorry, I meant the SG switch is ON....OOOpps!


If you have the quiescent 60 mA idling current, it has to be something
else besides the finals. There's no drive, you'd see the plate current
go up when peaking the preselector.
A dirty switch contact, etc. Something simple I'd suspect. I doubt the
driver tube went bad sitting... Also, it is probably more "touchy"
to replace than the finals; I've seen big differences between American
and imported 12BY7 tubes! (I assume that is what they use, IIRC.)
