OK, now the rebuild is really complete. Yesterday I added the relay
to take the load off the On/Off switch. Here are pictures and a
description of what I did:

Before the addition of the relay, I measured a current draw of about
325 mA with the power supply unloaded. This would also be the current
on the On/Off switch contacts. Since this was on an unloaded power
supply, I would expect this to rise when transmitting.
After the addition of the relay, this current (from the relay coil)
seen by the switch contacts dropped to just a bit over 10 mA. This is
a substantial drop, and should make the switch contacts last much
longer.
Oh yes, comments, corrections, and suggestions welcome.
