[R-390] FS/BO: Collins 30K-4

FS: Collins 30K-4 Vintage HF Transmitter.

Taking offers on my partially restored 30K-4 xmtr.
Several years ago I acquired this rig with the idea
of restoring it after retirement. The time has come
and I have come to the conclusion that I bit off
more than I can chew - not technically as it is very
easy to work on (in 5' rack) and straight-forward
circuitry - but timewise. I have been putting about 75%
of my spare time on restoration taking away from
projects that I am now more interested in (i.e., VLF,
antennas, D/F).

It is about 75% restored. On all the individual chasis
they have been cleaned and things like xfmrs, chokes,
etc. were removed, cleaned, repainted, replaced, etc.
Only the cabinet (5' Bud rack) remains to be refinished.
Most of the components have been checked by applying
either 110vac (via Variac) or B+ (variable 0-500vdc
supply) and slowly bring up the applied voltages to
season the electrolytics, check insulation, etc.

It is missing the tubes (6V6, 807, 4-125A in the RF
and the speech ampl/mod tubes). It has the 3-5 mhz
RF coils & xtals. It is unmodified in anyway. The
only addition has been a set of heavy casters so as
to move it about but I plan to remove these so it is
"virgin"

Digital pix are available (complete unit, before/after
of each chasis, etc) to the seriously interested. It
comes with a copy of the complete manual.

I am not interested in donating it and have a lot of
work in it along with the original price I paid.
Naturally, a pickup deal would be ideal as it probably
weighs 500 lbs or better.
