Soon we will all get spam mail on how to get big peckers.

Anybody has experience with the materials from this site?

http://www.lessemf.com/mag-shld.html

Thinking of getting the Magnetshield 4 inch ribbon, wrap it around a big tin can (a few layers?) and covering the trafo to see if it helps.

Why are we so fastidious when preamp manufacturers seems to have no problems? Don't see many 2 box solutions for commercial preamps.

Maybe I should look for smaller trafo - maybe 100VA - except it is hard to find a 80-100VCT small trafo. Any sources?

Your reference is no good. With commercial amps price is one of the biggest goals. For price no object brands, your statement is incorrect. There are solutions with two boxes, batteries...
It never ends of how it could be done better.

Go for reasonable size trafo stick it in the furthest corner of your preamp, and you will be fine. Or, turn on your preamp and amp, move trafo around the box and outside the box and listen. Where you here the least amount of noise set it there. Obviously make sure that you have no power when you are touching trafo.

You are wrong.

Placing the transformer in a separate small shabby case is very common, the ones which also have the rest of the PS in a separate box are un-common and only a handfull.
There's even a straight-6 boxer pre-amp.

(can't wait to hear what the Woody-Pecker has to say about transformer size)

why - that can be really overwhelming experience .......

AR2 is right - in many commercial preamps man can find eeny weeny xformers , which radiating field is way weaker than of any xformer you (hershann) posted ........

on the other side - Pumpie with Shunty isn't everyday's preamp ...... just look at amount of energy it needs, without any additional fancy gadgets

I think that a hi end preamp in 1 chassis has probably gone thru much R+D in this regard. The maker likely went through several layouts and several trafos before settling in on an arraignment.

I'd rather just stick it outside
