Here's my rewound xformer. Last time I checked, it put out 2x27.5V with 124V on the primary. That's going to get used for an amplifier soon. I did 2x25 turns of 14 guage solid wire. The fit is so tight that I had to force the last 10 turns into the holes. BTW, the scratches on the core are from me cutting off the secondary with a hacksaw.

so you have 2 pairs of wires respun as your secondarys? and it pushes 27v dc on each 1?

xplod1236 · 7th March 2006, 04:32 AM

2 secondaries that put out 27v ac each, so it should give me at least +/- 35v dc.

WordUpOnLCDs · 7th March 2006, 04:35 AM

ah, so how do you get it to ouput dc? and do you know how much current its pushing out?

xplod1236 · 7th March 2006, 04:40 AM

You run the ac thru a rectifier. I'll be getting a few of those shortly. I haven't tested it yet, so I don't know how much current it's pushing out.

well keep me posted on how it goes, this is helping me very much.

IIRC you have to get a bunch of glass pickling jars, aluminum plates and some Lye solution.

Oh, never mind, I thought I was replying to an OLD post

my mot is so much smaller than yours, think its still possible to draw useable power out of it? like 12v at 20a?

12V at 20A is only 240W, a microwave oven transformer is rated about 1000W - so there's no problem as far as size is concerned!.
