Merit plate transformer that I was using to power an 813 cw transmitter now de-commissioned. Nothing else in the pictures is included this offer. It has a one secondary winding with 1800 volts tapped and taps at 1600.
I used the 1800 volt taps into a bridge rectifier, gave about 2500 volts . Its been in use for several years with no problems, has plenty of scratches patina. If you use it as full wave tapped, can get about 1260 volts or 1120 with capacitor input filter.
This transformer has one 115 volt primary input. The output leads were cut short when I got it, added several inches using test prod wire and wrapped area with Teflon tape.
