TCZ ([Milsurplus] Re: FTC gripes and (to stay on topic) ART 13 qstn

[WA5CAB at cs.com]

I think I know of two, maybe three, people who've said over the years that 
they have one or the other supplies.  Courtesy of a list member, I have about 
98% of the TCZ-1 and TCZ-2 Instruction Book available as a reprint.  Difference 
between these two is only which supply was furnished (which depended upon how 
old the ship was that it was bought for).  Components are almost all the same 
(except as far as I can tell the antenna loading coil assembly) as in the TCZ. 
 Except that only one supply was furnished.  In typical Navy fashion, new 
contracts, new model numbers.

The DC supply has two large dynamotors.  The AC one has a 
transformer-rectifier supply for HV (as Dennis said) and a motor-generator for LV.  Both are 
large/heavy.  Definitely boatanchors.  The IB does not list serial number ranges 
so no data as to how many might have been produced.
