Power Transformers; 175VA, 36VCT at 4.8A

[dozer]

As I was working in the trailer today packing a function-generator for someone, I came across some neat audio-project parts that I'd forgotten I had....

High quality 175VA power-transformers made by MCI Transformers in Babylon NY.

They make a very useful output of about +/- 24 vdc bipolar, at no-load and nominal line input.

Rated 36VCT at 4.8A continuous-duty, and come with dual 115/230 primaries.

Note: it's not just center-tapped, it's two separate windings (4 terminals); so you can easily parallel the secondaries instead, for almost 10 amps at 18vac.....i.e. about 7 amps continuous DC at 24vdc output.

It weighs about 6 pounds, and features easy 'quick-connect' wiring.

This is a current product, part# 4-49-8036, with full specs at MCI's website: http://www.mcitransformer.com/i_4-49.html

Another feature nice for audio: "MCI's split bobbin and non-concentric winding provide better insulation and high signal-isolation, thus eliminating the need for electrostatic shielding."

I think I have about half a dozen of these left....they're all brand new, never used, still in factory-wrapping, as you can see in the pic.....but have been in storage for a few years, which affects the surface-finish a little.

Full set of pictures at: http://www.oregonstone.com/TR-MCI-175va.html

I believe these are currently around $40 in singles from the factory.

I'll sell a single piece for $19, or a pair for $33, plus shipping.

And none of those BS extra 'handling' fees like on ePay either....lol....

I am sorry, but I cannot ship out of the US.

ps; if you want all six, I'd take $90 for the lot.

thanks,

Richard

Thanks for moving it Cal...

Hi Dozer,

For members reading this, it would be perfect for a LM1875 application and with 175VA a stereo bridge application. I'm listening at the 1875 as I write this What a nice sounding IC

Take care,
Eric

hi Eric

Thanks much for the info on the 1875 chip.....I hadn't thought of that one.

hi folks,

All the MCI transformers are gone now.

Thanks, and I hope they power lots of good music from your projects for you!

ps; I just found a pair of smaller units today....same 36vct, but 100VA...which I'll start a new thread for when I get a pic taken.

pps; Mods....for some reason, I can't seem to edit my thread-opening post, so I couldn't change the title to say 'SOLD'....save people from wasting time reading the whole thread....so if you could do that for me, I'd appreciate it.
