[GreenKeys] Teletype Wheatstone Perforator

[Nick England]

I was given a nice 120v switching power supply that I now use for all my
120vdc stuff.
Before that I hooked a bridge rectifier and electrolytic up to a small
variac and plugged it into the wall - be careful with that!

The 120v coil in mine measure 86 ohms, so 1.4 amps
There are several different coil voltages - see page 7
