I'm still struggling with this
Philco 50-920 I've been writing about for what seems like
recapped it and had all but about 4 or
5 resistors out of 15 replaced (13 out of 15 had really
badly). Radio was playing loud and strong at that point but
with some intermittent static and "cutting
out." I decided to replace the remaining resisitors--what
left were 4/5 resistors between the power tube and
rectifier and one across pins on the power tube (50L6).
After completion with new resistors, fired up the radio. No
static and no intermittent cutting out, but I lost just
about all the
volume. Full volume setting on the switch and I hear a
station weakly. I checked tubes...still okay.
I decided to check the resistors again for values. All okay
except a 470K resistor between power tube and rectifier was
about 343 ohms in circuit. I took it out of the circuit and
at 460K. When I put it back in the circuit, I clipped one
(didn't solder) on the power tube. It read 460K across that
When I clipped the other lead on the rectifier tube lug
belonged, it dropped to that same little 343 ohm reading. I
think this is
the cause of my diminished volume but I sure could be
wrong. It seems
as though the 35Z5 rectifier is glowing too brightly under
with that resistor connected.
Anybody have a clue what I'm doing wrong? I know I've
something but I'm totally at the end of my wits. A radio
looked at it with me last night. Neither of us can figure
it out. It's
what I get for trying to tweak it some more I guess.
Any help will still be appreciated.
