what should I do with this tranny???

[mylesmf]

Hi Everyone,

I have recently obtained (for free, thank you very much) a Gardners power transformer with the following specs;

155v, 45v, 100-0-870v, 6.3v, 13.5-0-13.5v, 6.3v, 6.3v

I am a little uncertain as to what I would build with it though, I would like if possible to power two channels. What are my options as to configuring the power supply and what would be the most appropriate use of a tranny like this. Anyone have any ideas I'd love to hear them.

Thanks,

Myles

It's impossible to give advice until we know how much current the secondary windings can deliver. Any idea?

If you don't know the current, the physical dimensions of the transformer would be handy in guessing the VA rating at least.

Your transformer looks as though it came out of an oscilloscope. If that guess is correct, then the 870V winding will only be good for a milliamp or two, and the 100V winding for about 10mA or so.

the value of free trannys

Unfortunately the transformer is in London and I am in Barcelona so I can't check secondaries right now. If it's any help the thing weighs a little over 2kg (5lbs), stands about 8 ins high by 5 wide.

If it did in fact come out of an oscilliscope should I save myself the shipping and politely reject it?

Thansk for the help

If it's that size, then it's probably useful for something. It would have to be a very big oscilloscope...

Never reject good iron....

1) You'll figure out a use for it five minutes after saying "no".
2) That big and if out of a scope, imagine the filaments you could power!
3) You can rewind it.
4) Trading power!
