[AMRadio] WTB: 500 pF Centralab 850 doorknobs

[Mahlon Haunschild]

Gang,

Checked the aux. coupling capacitors in my Johnson Thunderbolt
yesterday.  EVERY ONE OF THEM IS SHORTED.  What is it with Sangamo cast
mica capacitors, anyway?  Every one I've come across (just the ones with
the solder tabs) was shorted.  All the other brands (Sprague, Aerovox,
and one other) appear to have stood the test of time perfectly well.

So... Anyone got some 500 pF Centralab or HEC 850S doorknobs that they'd
like to sell?
