Default cheap gc transformer source Canadian

Just built a 3875 gc with 250va industrial control transformer works and sounds fine. These are 600 volt in and center tapped for 120-240 v out . Feeding it with 120v gives me +/- 33 v dc into the amp cards . These transformers are very common in industrial surplus and readily available. Were used for getting control voltage in industrial panels in sizes up to 1 kva.

Just look up a salvage yard that deals in industrial panels , I am an industrial electrician and come across them all the time. I didnt mean to say I have them for sale , most makes are Hammond and Marcus.

You guys live in Canada so why not order them from Plitron? They make excellent transformers and it won't cost you as much because shipping shouldn't be bad at all. Heck, you might even be able to go order and pick them up in person!

Ah I see. That's not too bad of a price. Only slightly less expensive than Plitron!

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

Hey mercator, I think we were probably looking at some of these on our last Calgary Metals trip. Next time let's bring tools.

Ive noticed a consistant trend of large savings whenever you buy components that do not have anything to do with audio. Its really extreme when it comes to silver wire.

The surplus market of industrial equipment is so much larger and its market serves penny pinchers. Good luck finding audio power transformers at dollars/KVA.
