Hi Phil.

Thanks for that, you highlight my dilemma well. I don't think many people
realise that PCB's have been around for as long as they have. I only
became
aware of the possibility when I came across a query by P Bertini. The
simple tests suggested by AndyB above look promising in this regard.

He claimed the capacitors had PCB dielectric, something I've never
been able to confirm. A few other restorers have claimed that the
original metal capacitors were leaky enough to cause AGC and
other sensitivity problems on their AR-88x receivers. I haven't
worked on or restored mine as of yet, so I am neutral on the whole
issue.
