[Hammarlund] restoring SP-210X

[gary hildebrand]

I've taken on the restoration of this gem, and am in need of some parts . .
.

So far, I'm rebuilding the RA-84 power supply with electrolytics (the
original paper caps are gone), and replacing the old wiring with new plastic
insulated wire and fuses for the B+ lines, and of course the obligatory 3
wire line cord.  This restoration is limited to front panel cosmetics, and a
working receiver. The previous owner had added a couple large 10 mfd @1kv
paper caps, mounting them to the front panel . . . YEEEEECH!!!  And put a
pair of filter chokes in on the bias supply.

I'm planning to use perf board, and Sprague TVA electrolytics, 10 mfd or so
@450v, if the unloaded B+ is about that.  Should I go 500 or  more?

I have only two of the original small knobs, and depending on price, would
like to make a complete set.

I also need two of the SPST rotary switches (Limiter off/on),
(send/receive).  ISTR Switchcraft made some that looked like their toggle
switch bodies with a shaft out the side, and a half/moon bulge on one side.

I'd like to find a proper name tag for the front panel, BC1004, made by
Wilson.  The power supply still has its label, and it is made by Wilson.

Any good ideas on a cover over the power supply connections/fanning strip?
I was thinking something like 1/2 of PVC pipe, or equivalent.  I want to
make this safe enough for anyone to be sticking their fingers in things and
not getting kicked across the room .  . IYKWIM.

Other than a paint job after filling in extraneous holes in the panel, it
looks like there hasn't been any other hacks applied.  It's a shame to see
something this well built hacked by schlock repairs, and wiring with
friction tape . . . !?!?!?!?!?  I can fix that . . .  Add to it a nice
speaker and box from a car stereo shop, and matching transformer, and I
should be in business.

Thanks for your time and help . . .
