Tom, thanks, follow ups below please?
"For a direct line powered radio like one of these, the return for resistance and voltage measurements is the B- connection (minus of filter cap), not chassis ground. For transformer powered sets, chassis is ground. Resistance is always measured cold (unplugged)."
Makes sense as I am measuring voltages at various points along the B+ power circuit. To clarify, the set should be powered on before I CAREFULLY measure voltages, but measuring resistance on tube pins is done cold, again with negative lead clipped to B- unless otherwise stated? Also is it real important to use VTVM for measuring resistance in this instance?
"It's a good idea to check for voltage on the filter caps if there's any doubt..."
Um, forgive me but what does that mean, if there's any doubt about what
Fisherdude, thanks for the welcome. I noticed you posted a long reply earlier that I was excited to read when I was not at work but now it is gone. I hope, if there was good info., that you will share? Many thanks.
