I'm looking into this power transformer that I got out of a 1950's Capehart-Farnsworth radio / record player. I was initially considering it for a tweed champ or 18w Marshall build but am now thinking of trying the power transformer in my tweed deluxe clone (it fits the cutout in the chassis exactly). I have a classic tone in there now and voltages seem okay. But curiosity will be the death of me and I can't help but wonder about how it will sound with lower voltages. It wouldn't be too much hassle to swap it out but I want to make sure I don't blow up my amp in the process.
I wired up the primary of this 50's PT to the wall @ 119VAC and took AC readings off the high voltage line, which came out to 330VAC to center tap. I guess I'm not sure what that will result in when under load in an actual amp circuit. Ideas?
I'm also unsure of the current the transformer puts out, especially on the high voltage secondary. Can this be calculated from the tube chart of the original radio it powered? I'll attach it here as well as a grainy schematic of the original radio.
Thanks guys!
