I've got the whole manual for Rectifier Unit CCSM-20218B, the 120 volt power supply for the TCS transmitter/receiver.

They are too big to attach here, about 8 meg each, in PDF format.

While I'm at it...does anybody have a power cable for the transmitter? It's got a 16 pin Anphenol connector on each end.

Also, I need a filament transformer for that power supply that I cooked this last weekend on the USS Torsk (SS-423), my old boat. That set is 1944 original to the boat, although I'm sure it was using the dynamotor supply then. The AC supply is from the late 1950s.

The transformer is T-303 and supplies 12.6 volt CT @ 3.9 amps and 15.1 volts at about an amp.

A cable short pulled about 8 or 9 amps through the 15 volt winding and a 2.25 amp selenium full wave bridge rectifier to cook the transformer, without blowing the 3 amp primary fuse or cooking the rectifier. I've got a hambone fix running it now but I'd like to get it back to original.

Hey Greg,

    My AC supply is designated "PP-380/U", Mine also
lost that xfmr. I did the same thing it sounds like you
did. Plenty of room for "Extra's"!

It looks like yours uses the same interconnecting cables but the one I've got looks quite a bit different and has a metal mesh cover. The thing weighs at least 75 lbs.

I'm still looking for an original or close to original transformer since the thing sits in the radio room of the museum boat.

I don't suppose you know the location of any transmitter or receiver cables?

Out receiver cable still works but is in ratty condition, the transmitter cable is dead. I found what was supposed to be a TCS cable in nice shape for a good price but it had the index rotated about 90 degrees from the TCS one. I checked that all the pins were hooked up, which they were, and then ground a new index slot in the plugs. The only thing I hadn't checked out was that pin 16 (power for the relays) is also grounded to the shell of the plug. This shorted the relay power to ground which didn't blow the primary fuse or the 2.25 amp selenium full wave rectifier but did burn up the transformer after about 15 minutes.

Now I'm looking for a transformer that still has it's potting material and magic smoke inside!

I could use a copy of the manual.

Hey Greg,

My Cables can be disassembled, They just
go together with those large knurled Threaded
sleeves. The connector itself comes apart
with three small screws. I should think you
could pull new wire into it since all the
"Cosmetics" are there.

  I see TCS cables on E-pay from time to time
but that black jacket they used didn't seem
to stand the test of time.  Modern "Liquid
Tight" flexible conduit may be a good substitute
but haven't looked into it.  I believe each of the cables
had a right angle and a straight connector.
the right angle conn. can be rotated by removing the 3
screws. One of my right angle's was sticking sideways.
It was an easy fix.

I shipped it off in three parts.

I've pulled the plug covers and I should be able to swap a couple of wires and make this cable work. If I could find another proper cable I'd probably buy that rather than fight with this one.

I did buy a very close transformer off of Epay tonight which should work just fine and look pretty close to the original. There again, I'd buy an exact match if it becomes available. 12.6 vct @ 3.9 amps and 15 v @ 1.0 amps. Potted.

Thanks!

Greg
