Plate voltage on a Philco 37-650
#7

Hi Again
Thanks for the schematic,looks like I am 100 volts over on the 6F6 plates,the set will run
for an hour and a half fine then the speaker starts making a noise like it is torn or there
is something leaning against the speaker cone,I tried three other speakers same thing.
Do you think it is from the high voltage on the plates,is there a way I can bring it
down close to where it should be without burning out the transformer,I can run the
set now for four hours and the power transformer is not hot just a bit warm,I could
hold my hand on it as long as I want,runs rather cool for a power transformer.After
about and hour and a half I put the base on min. and turn down the volume,thankful
for any help,all the best Rick

Thanks Morzh. So it appears I did wire it incorrectly and I have to switch the wires between pins 2 and 4.bobclausen — 09:24 AM

No, it's not a problem, just during certain condition it could show up. Yes, an internal tube short could do that too. ...morzh — 09:13 AM
