Avel Lindberg is all right in my book.
The thing about VA vs. Watts is that sometimes it's apples to apples and sometimes it's apples to elephant boogers. Setting aside the relative quality that you might expect from one manufacturer or another, the VA only equals W if the load is purely resistive. Once the load becomes reactive (not to be confused with radioactive), then you get into power factor correction. Depending on how far off the current and voltage peaks are from one another, you can get wildly differing numbers.

ANTEK
I use these puppies from ANTEK 18v+18v @ 400VA.
No problems with them. I think Nelson tested a members at one point and found them acceptable. They are fairly inexpesive.

Re: ANTEK
Oh heck!!! I just remembered I have 2 of these same ANTEK 18-0-18 transformers new in the box in my garage after changing my mind on a prior A30 build.
That saves me $94 from Parts Express for the Avel's. ANTEK's work very well. I have a 650VA Antek in my current A30 with excellent results.
Thanks mithomas for the memory jog.

I am running those same Anteks in mine, they somtimes buzz (physicaly) when my fridge is running other than that they work fine. There has been some discusson as to thier quality, having tried Avel, Plitron, Antek - Plitron was clearly the superior however at roughly twice the price I can put up with little hum. Evan Nelson rejects some Plitrons due to noise. Sadly as many amps as I build cost is a big factor and I hunt for bargins and live with the short comings. Apex does offer some bargins and they are not always posted on the web site. I always give Steve a call and check- He will be getting in some 1KV - 55v toroids in Dec at $30 bucks a heck of a deal.

Hi Bill,
I had a similar experience with my Antek. The thing is absolutely silent, except when my front porch is turned on, then there's a slight buzz coming from the transformer.
The Avel Lindberg Y23 model in my BOSOZ preamp is perfect under all conditions.
How funny.

I would absolutely buy an Avel over the Antek.
The Avel 250va 18-0-18 from Parts Express for $50, no tax and free shipping special under way.
The Antek's are good and the eBay who sells them is first rate to deal with. Owning both, the Avel is much better made.
Just my $.02 worth,
