I made this enclosure to house my Avel Isolation Transformer. It is to tidy up the look of a raw transformer just sitting on the carpet. I now have it inside my entertainment center. I just need a polk audio emblem for the front and to fabricate the top the next time I have my table saw out.
I like speakers that are bigger than a small refrigerator but smaller than a big refrigerator:D

    That's nice Scott. How about a smoked plexi top?

    I planned on doing a black oak top of course. Not that much to see inside except a big **** toroidal and a couple of leads.

    Question. I hooked it up using both the primary and the secondary winding this time istead of just the primary. The wire sizes are different between the primary and the secondary.

    Do you think that would/could /should make a difference?

    Please tell me you are not using banana plugs for 120 volts AC.:eek:

    Well the primary would be the input and the secondary would be the output so can't see how it would work otherwise.It looks like your tranny has dual secondary outputs so you would run them in parrallel.

    Looks like you configured it with Primaries and Secondaries Parallel Connected as per Avel's diagram for Y23 Range Transformer Connections:
    Left Blade = BLU/VIO
    Left Pin = GRY/BRN
    Right Blade = BLK/ORG
    Right Pin = RED/YEL
    Is this correct?

    What about a piece of smoked lexan for a top cover?

    Doh,:oI must apologize for my ignorance with my previous reply in this thread.I thought originally that Scott meant this Isolation transformer was for 120 volt AC usage thus my comment about the binding posts.I now see it is part of the specialised setup to use SDA's with non common ground amps.I was not previously aware of the need for the transformer.

    Scott, this is to make the cable that would allow you to use monoblocks, right? My NAD 2200 is bridgeable, so I'm definitely interested in how it works!
    Good music, a good source, and good power can make SDA's sing. Tubes make them dance.

    Even with the A1 I don't think it would be worth it to bridge. Which SDA's do you have?

    My amp is dual mono configuration so after consultation with those in the know I used the Avel isolation transformer for my SDA's. I built the enclosure because I thought it was better than just having a 13lb transformer sitting on the carpet with wires attached to it.

    Wala I have something that looks like something and keeps electronics from going poof.

    I actually milled the top for it on Sunday and painted it. To be honest I have not even seen what it looks like with it installed because of where I have the enclosure sitting right now.

    With blue lights on the inside!!!:eek:

    I think the smoked top would look cool. But if it's stuck behind the equipment rack where nobody can see it, then . . . . .

    Hear is the lid I made for my Avel Isolation Transformer. Nothing special.

    Do you guys think an old school polkaudio emblem would look good or a newer style emblem? I was thinking of putting it on the face.

    I also put some feet on the bottom.

    I would keep it clean and just throw some feet on it.
