Does anyone have a 1kC crystal in octal tube format they can spare? If so, Please bring it along so I can test my BC-221-M, and work a deal if it comes back to life.
Running out of parts to replace on this puppy. Unit is still dead, all tubes VG to EX, I’m down to a few small coupling micas to replace (#44, 5 pF is my current suspect for those who feel like looking it up on the schematic)
I’ve replaced bathtubs 43a/b, 7a/b/c; big micas 8, and 9. All were leaky. #10 bathtub tested fine.
I’m not sure my crystal is even oscillating.
This unit and my LM-13 both used to work, but are now silent. Tubes are good, and I’m using the same PSUs as before.
Scratching my head.
See you all next week!
