If you're still able to receive using the transmitter to control, then your supply is probably okay, since the low-level tubes use the same +250V supply (other than PA plate and bias). If you're still getting 70mA of idle current, that would make it likely that your PA plate and bias supplies are also okay.
Loss of any of the low-level part of the chain will give you no output. Check all the oscillators for signal presence. 73, Steve Wedge, W1ES/4 Live free or die: Death is not the worst of evils.

Still no out put other than idle current when in tune position or when PTT is pressed now.... Maybe a blown Diode or cap in Power supply??????What do you think? 73 de Fred WD8ADG -------------------------------------------------------------------------------- _______________________________________________ Drakelist mailing list [email protected] http://mailman.zerobeat.net/mailman/listinfo/drakelist
