[ARC5] Command Transmitter Bathtub Capacitor Replacement

[Brad Hernlem]

If you don't want the mica plate intact, you can perhaps pry up the edges of 
the metal can, release the mica and replace it with a PC board terminal 
disc. It won't look exactly original but then you may have a hard time being 
perfect.

If you wish to dispense with the tubs entirely, here is what I did recently:

I soldered these right onto the tube sockets and terminal boards to keep the 
wire runs very short.
