[Boatanchors] FS: SSB Product Detector for Collins 75A-3

[Charlie Hugg]

FS: SSB Product Detector for Collins 75A-3. Universal Services Company of
Columbus Ohio, the main Collins dealer at the time offered a Product
Detector that plugged directly into the NBFM socket of the 75A-3 receiver.
It has a copper plated chassis and the passband control went through a hole
that was drilled in the front panel of the receiver by removing the Collins
winged emblem. This one does not come with the linkage to bring control
forward to the front panel, but it should not be hard to find. I used it on
my 75A-3 by changing the passband from Lower Sideband to Upper Sideband by
opening the top lid and manually changing the position of the detector. The
Model # is A2-3. It comes with a copy of the manual. It works great. There
is some corrosion on the copper chassis. Pictures are available. Price is
$115 shipped CONUS. Thanks, Charlie Hugg, K5MBX, CCA# 96-003-007
