[ARC5] AM-40/AIC-4 interphone amp

[Michael Hanz]

I notice another ARC-5 associated interphone amplifier is on the bay,
for anyone looking to complete a set - it's number 1065441888.  These
actually clean up fairly easily - this is an early one, which like mine
has heavily etched nomenclature markings which stand proud above the
panel surface by a good deal.  That makes a black wrinkle repaint and
subsequent sanding of just the tops of the numerals an easy thing to
do.  I have no connection with the seller - just passing on an uncommon
opportunity someone may have missed.

Best 73,
Mike
