Re: Philips BX281U20 valve radio
Em interesting since just taking readings keep losing rf signal completely then bit fiddling on knobs pulls rf back in!
I think I might need to clean up the radio wave selector wipers see if that's the problem as I'm getting lot of static switching back and forth!
If not solved I might change the resistors as I've had it running for 3 maybe 4 days can't remember without problems so now everything has had time to heat up and run as it should maybe it's causing weak spots in circuit to break down starting to cause problems just a thought!
Capacitors are fine so either resistors, wipers or valves. Got NOS rectifier so could be UBL21 don't think it's UCH21 as there not really stressed as such like the UBL21 or Uy1n.
Any thoughts?
Cheers Chris
