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 ampsThere are several different coil voltages - see page 7https://www.navy-radio.com/manuals/tty/1025B-3710.pdf   Nick England K4NYW

 Some time ago there was a discussion on a heavy duty DC power supply for the Wheatstone Perf. (WPE3/ISS)
 
 And I believe someone made one for it.
 
 I would like to build one and am looking for part #s and specs.
 
 I am sure it would take more than 300mA!  :-)
 
 Any help appreciated.
 
 Thanks in advance!
