I assume mull3t already hooked you up with the small but mighty Amveco 62043-P2S02?

Good timing - I was just surfing threads trying to track down that transfo :-) I remembered that Mull3t spoke highly of it.

I did indeed use the Amveco and have to give credit to jdkJake for that find.

MrR -- I think I recognize that case po1019 from eBay did a fantastic job with my case. I would buy from him again.

My Amveco just landed; can't believe how much smaller it is. Yea, he really does do nice case work. I've bought 4 from him so far for various projects. my only 'nit' would the opening being on the bottom. It's not necessary to use it that way, but if you want seamless lines...

I believe his cases are designed to be tube amps hence everything is upside down. I decided to have him do all my drilling, etc. and have him flip everything. I don't mind not having the seamless lines. It still looks good.

Yep, I think you're right. I did the same with the cases I bought from him for my DAC's (pre-drilled). For the cost - such a deal.

Need a bit of help with the Amveco. So for 115, Red+Yellow to Neutral. Just not sure about the secondaries. I'm hooking them up to the Wire PS. I have Blue, Red, Brown & Green in order. Guys?

I've never used the Amveco transformers but digikey gives this diagram on the page for the model linked referred to by jdkJake earlier

http://media.digikey.com/pdf/Catalog...0SCHEMATIC.jpg

So keep the secondaries in the same order for each half of the PSU, the dot indicates the start of the winding.

IF that is the diagram that corresponds to your transformer then something like:

green-red, brown-blue

should do the trick. But your order seems different to what the diagram suggests. Is there a similar diagram stuck on the side of the transformer?

Yea, that's it. Hmmm. I have Red+Yellow to Neutral, secondaries are paired as you indicated. Does it matter the order? (greed-red vs. red-green)? Get a loud hum when I power up.

It's working. Ya know, old age sucks. I strain to see clearly and it burns me time and again. I didn't have both pins on the power connector. Thanks for your help mate.
