Default Vintage Pioneer SX-838 receiver loses one channel after warmup

After all that aggravation with futilely tearing apart the carb in
frustration, I guess I was due for an easy layup with the Pioneer. I
guess I was tricked by the fading out and fading in into thinking it
couldn't be the speaker relay. I have never been so happy to be wrong!


But next tiem you rip into the carb it will only take you 25% of the time!
Ha ha, too bad you probably will never have to. I had a similar situation
with my car last year, it turns out I had an extra fuel injector in the
throttle body for cold starts which kept coming on when it shouldn't... that
was a WHORE to track down, it took MONTHS of replacing suspect parts.

Good news on the Pioneer though. Dirty controls and relays are, as I said
from the git-go, by a factor of about 10X the most common ailment these old
dogs have... oxidiation is unstoppable even in dry climates. The great
thing about this group (and others like it) is that there is probably a
combined 100 years of tech experience monitoring the posts at any given
time...
