Hi Jeff,
Wow, what a mess of replies you got, but nobody offering to sell you
one.
I have 2 possibilities:
1 - what appears to be a hombrew "repackage" of an AC-3 on a small
chassis. It looks like the components are from an AC-3. I powered it up
some time ago to ck voltages, seemed OK, but I didn't put it to any rig.
It needs am AC cord, and has a female jack for outputs.
2 - a stout HB supply in a covered chassis like they used to put audio
amps in. I used this for a while with a T-4X. It has a terminal strip on
the back, and a cable with the proper Drake plug.
I can take digipix of both.
$25 for #1
$50 for #2
plus postage

Subject: Wanted: Power Supply for TR-4C


Wanted - Cheap - for Drake TR-4C: broken AC-4 or AC-3, or home brewed

power
supply, or modifiable power supply by other manufacturer, or interesting
power transformer.
--------
I want to power up a Drake TR-4C I picked up. It did not have a power
supply. The price an AC-4 power supply brings today is more that the
transceiver is worth. Are there more radios out there than power

supplies?
(Kind of like there are more horses asses than horses). Are the high

AC-4
prices a function of scarcity or what?

I've looked at the schematic of the AC-4 and decided that it's not

rocket
science. I'm not putting together an "original" collection of Drake
equipment and I don't need the power supply to fit within a MS-4 speaker
(which I don't have and don't need). So - I think I have some

economically
appealing options.

- I could repair a broken AC-4, AC-3 as long as the transformer is OK.

- Home brew power supplies do not scare me.

- It's possible power supplies for other rigs could be adapted to work

with
Drake gear.

- I could build my own homebrew power supply. The critical component

would
be the power transformer / transformers. (There are many power supply
designs that would work).

Here is what the power supply needs to do:

Input: 117 vac
Outputs: (12.6 vac @ 5.5A), (650 vdc @ 300mA average - 500 mA peak),

(250
vdc @ 175 mA), (-45 to -65 vdc for bias)

If any of you have something to sell me that will get me there, please

let
me know (with details).


Thanks Jeff - KA9S

AC-4 supply with this board.
