Hi guy's,
Brought an old 630 home and hooked it up to my variac.
All tubes light as well as bulbs.
Has no sound at all, not even hum or static.
Tried swapping a few tubes, but no luck.
Lookes like someone years ago replaced a couple of the electrolitics. Did a messy job of it too.
I replaced those 2 with no change.
Any suggestions on what I should check next?
I am leaning toward output transformer or maybe even speaker?
This looks to be a difficult one to work on. Typical Philco I guess.
Thanks,
murf
