I'm trying to use a somewhat generic universal chassis labeled, "H-12" on the board, and "EPSP648" in some places in the listing I bought it on. I can't find much information about it. The tube I'm using is labeled WG 1220872. It came to me in an otherwise empty cabinet. No boards/chassis etc, but was told it worked.
Anyway, I can't find docs on this exact board, but from reading various sources, I thought I had things hooked up right. However, whenever I power it on, it pops the circuit. I am not using an isolating transformer but thought I read newer chassis didn't need that.
When I measure the windings, I get 2.3 and 5.6 ohms.
If there are other pictures or measurements needed, I'd be happy to provide.
