So, I guess my FIRST question is what the meter movement is. I gather
from the schematic that it's an ammeter but I don't know what resistance
or full-scale current.

Offhand, the meter os 0.5 mA FSD, scaled 0-15 and 0-600. I'm not sure what
the internal resistance is supposed to be (all the ones I've just looked
at say "WS19 Voltmeter", which is not exactly helpful[2].

Okay, so I can try a generic 0.5 mA meter out of the junk box and probably
expect it to work. I can do that.

Ah... by "Pye sockets" I assume you mean the power and control ones?

("Pye connector" usually means the antenna connectors, which were used
on all sorts of kit.)

Yes! Also, the "key" connector appears to have more than just key contacts
on it!

Can you get the solder cleaned off the pins, or are you looking for
replacement power and control plugs as well as the sockets? I've got
a few spares but am on the wrong side of the pond so shipping will
take a while...

I can easily clean the solder off the pins; I have an SMT workstation
with the hot air and vacuum stuff. So I just need the sockets.

I don't think I am going to have the time to get this one up and
running for Field Day. This year anyway.

It's good to have a hobby.

So, since I have just the single No. 19 set with none of the accessories,
what is the easiest way to use it? I can take the antenna lead off to a
roller inductor and then to a long-wire antenna, no problem. I can easily
use an existing power supply to drive it, or build one out of junkbox parts
if I can get the connectors. How do I connect a headset, mike, and key up
elegantly without using the outboard box?
