Hello
I got my Philco 37-650 set up and running,with a lot of time spent on it,I
played it about seven times for about four hours at a time,worked fine
never stopping,I have changed all caps but not the mica caps and about 90% of
the resistors.It stopped playing two nights ago,made me sick,so much
time and effort spent on it,refinished the cabinet and installed new
grill cloth.When it stopped it made a low crackling sound and died,I
left it for a few days had to get away from it,today I started to check
the voltage on all tubes when I got to the 6J5 there was no plate voltage
and when I checked the service data sheet I have it had no voltage for the plate
on the 6J5,is this the way it is no voltage on the plate ?.A strange thing happened the
set started to play again while checking voltage on the 6J5 a little bit of low crackling noise but came to
life,I had given up just too much work and those black tub caps are no fun
at all.I checked the voltage on the 6J5 with the set playing but nothing
on the plate,now as I played it the crackling noise was still there on and
off,so I don,t play very long at all, a minute or two at most,I am afraid it
will quite again and never start ,I used a probe and moved every wire
and joint I could see with no effect,any ideas where I should look,I
would be very thankful for any help at all,all the best Rick
