Amp is working......with a new tube. Thanks to all for the help and
suggestions. Checked transformer, checked filament voltage. Old tube
glowed nice until RF was added, then arched again. New tube works fine.
Repaired meter switch tonight. Before only HV and plate worked. Now I
have Power too, I don't use ALC so I don't know.
I am getting old, but before I replace the switch I thouht I check the
idilling plate current (80 as specified) by shorting the keying line to
ground. Now that I have replaced the switch I get an idling plate
current of 150. I am wondering what this might fortell or what I might
check if all is not well???
Thanks for any help.
