I may have an Air Force tech manual on the 96D if you don't have one. I
worked on these transmitters while with the Air Force in England.

Ola John,
Yes, by all means, if you can restore it, (to original maybe)!
The things covered 160 to 10 meters, if you got all the RF decks with it.
It did AM as well as cw, the HV power supply for each cabinet was quite
handy.
Having said all that, and reading what you have so far, I would say if you
are just going to put it on the air, you have most of the makings right
now.
The modulator section is indeed missing, but I bet you can find someone
that has the pieces you would need. They are prevalent in the land to the
north
Canada. Loads of them were used/assigned to duty there. I think I have
some
photos of the system, I will send them to you directly so you can see what
the
system looked like in "full crye", quite the beautiful rig. Some of the HV
supplies ran
on three phase but some were also single phase, those are the easy ones
to get going.
A real nice rig, worth the effort, I think.
YMMV

I picked up this thing yesterday at a SK's wood shed for $50. It had been
sitting next to the ugly-painted BC610E, which recently went on EPAY.
The Wilcox 96D is < a foot wide, 6 feet tall, 300+ lb box. It "works in a
drawer", in that it can be slid out on rails, for inspection inside. It
was built in November of 1952. It has an RF exciter, crystal socket
inside, and an 807 driving an 813 driving a PAIR of 450TLs. Only the 807
remained in the socket. Plate voltage on the final was 4100 and current
was 0.6 - 0.9 Amps. It was a powerful transmitter in its day! The power
supply was separate, and it isn't certain it made AM or not. Frequency
range is ~ 2 - 12 MHz according to the dials. It has little doors which
open to expose the turns counters for tuning, and one opens to get to the
fuses and power relays. On top are a pair of balanced output studs. This
funky looking transmitter (slim) needs the final plate tuning cap, but
has most else. It is loaded with some good parts, including the turns
counter dials, two big slip stator caps, a can within a can neaturalizing
cap. The PA inductor is tapped at numerous points, an
d has a
second coil which can be slid into and out of the fixed inductor.
Now the dilema. Its certainly a different rig, but it needs to be tubed
with pair of paralleled 450TLs and needs the cap along with a few small
parts. Should I part it out, for something homebrew, like a balanced
antenna Tuner? Or try and restore 'er? I'd be curious about others
experience and opinions. BTW, I have three other transmitter projects
needing my attention right now. I got the Wilcox out of the truck bed and
plopped it out under a roof next to my shed this afternoon. Inside one of
the front doors there is a complete parts list and schematic!
