cheap gc transformer source Canadian

[Crash&Burn]

If anyone is interested right now there are some good deals on 800 - 1KVA ~30-0-30 CT toriods going on down town. About 30 bucks a piece which isn't as good as the control panels but still better then Plitron.
If anyone knows of 22 or 25V CT or DS 400VA+ in town please let me know.

Speaking about trafo.'s, I got this one from the local thrift store. [$2] don't know the capacity but it has dual secondaries [blue-blue;red-red] which measure 21.4 volts d.c; rectified; 14.2 a.c.each side. It's tamradio japan. Which chip would go well with low power?

Hmmm. well not sure of a good chipamp, but I know it should make a fine preamp trafo.

The Kookaburra preamp would work great with that trafo, plus many others I am sure.

Nice find.

Cheers!

Great! good to know. I could not resist the gleam of that copper shield.

I think that's means you could get 21.4-0-21.4 so that is enough voltage for most LM*s, although maybe not ideal, but what VA do you estimate it is?

Hey Russ, curious why you called it the Kookaburra, what's the aussie connection?

Hi Greg,

I called it the Kookaburra in honor of all my DIY friends in OZ, seems like I have quite a few of them, including you. Plus, Kookaburras make a lot of noise. Hah!

Cheers!

Well, if we're tramping around salvage yards looking for these, it would be nice to know what they look like. Like this?

Sorry I didnt get back right away , gone on a job site. Yes , the transformers you picture are similar , regular iron core types. What I was getting at is , I just built a 3875 gc with one in it and it sounds just as good as the others I have built with torroids from Hammond . You will find them in panels close to the main disconnect.

What kind of filtering did you do? Or did you go for the "have big *** cap, thank god GC has awsome PSRR"

[squarehdca]

I did no extra filtering other than what is already on brians boards . Shielding is a concern with some styles , but with the price of them , you can afford it.
