[Boatanchors] TCS noise limiter

[WA5CAB at cs.com]

Don,

It is a noise limiter adapter kit for the TCS receivers.  Works in any 
model from TCS to TCS-15 (both Collins and non-Collins).  I don't know of any 
other model Navy receiver that it would work in as the TCS's 12SQ7 circuit is 
a trifle unusual (2nd detector, 1st Audio, and BFO).  Probably about 10% of 
the receivers I have had through here have had a kit installed.

The complete kit consists of two boxes taped together.  One contains two 
spare tubes (12H6 and 12SQ7).  The other contains the items shown in your 
photograph plus an escutcheon plate engraved with the legends for the ON-OFF 
toggle switch and the new rotary switch (the rotary switch replaces the 
existing BFO ON-OFF toggle switch).  Fair had them years ago but I don't think that 
I've seen them in the catalog in recent years.  Can't recall what they were 
getting for them.  I have a bunch of them and currently sell them for 
$27.50 fixed price.

The spares box is the same size as the box in your photo.  The escutcheon 
plate is black with raised aluminum lettering and roughly 2" x 3". with two 
holes in it for the two switches (no holes in the corners).  You should 
probably look around the SK's shack for the plate unless you have it but didn't 
include it in the photo.  The spare tubes are less important.  There may have 
been a couple of pieces of loose wire in the kit as well (but I wouldn't 
worry about that).  I think that's all, but I haven't opened a box since I 
installed one in my TCS-14 about 16 years ago.
