I know that most of you who replied suggested that I do this before

realizing my mistake in expecting the balance control to reflect the
switching of channels at the PRE OUT/MAIN IN RCA jacks (duh...), I
bought some switch cleaner from a nearby electronics supply place,
Electrosolve Contact Cleaner for Electronics, made by MG Chemicals, and
used it on the push button and flip switches and on all the pots. Now
it's just a matter of wait and see.


Hope you worked them when wetted. You can reapply.

I worked 'em... I worked 'em GOOOOD

After all I been through? Damn straight I worked 'em

I have the local Jazz station playing and so far so good, but it will
take some time to be absolutely kinda sure. These old Japanese beasts
are such great machines I just hated to let this one languish. In the
meantime I fixed the reluctant tray on a NAD C-451 CD player. Apparently
the factory installed belt on these machines didn't quite cut it. This
one was reluctant to open fresh out of the box. A new 69ยข O-ring did
the trick. Next I have an Advent 300 and a Harman Kardon 930 that need
attention.
