[Collins] 75A-4 S Meter Pot Mod Hardware

[Chuck Kembring]

Hello All...
	I've been having problems with my 75A-4 S meter circuit for some time now
and have been working through it component by component.  What is happening
is as the receiver warms up, (and the time frame is not consistent) the
meter readings drop off, eventually to zero.  I can restore meter function
sometimes by turning the AVC to OFF from either FAST or SLOW and Always by
turning the receiver OFF. then back ON.  Most of the capacitors have been
replaced and the resistors checked.  The AVC voltage does not change when
the S meter problem occurs...
	Anyhow.... I'm interested to know if anyone out there has the bracket
(especially) and the 500 Ohm pots that are specified in the 75A-4 service
bulletin 2A. A drawing would be nice or dimensional information for me to
fabricate the bracket.  I would think that suitable pots would be available
from one of the  parts houses. This would be a nice kit to offer for us A-4
users...
Thanks,
