Yes, I do the same thing in the MDAC power supply I make. The standard MDAC supply is a AC unit, the MDAC itself contains rectifiers and regulators. But if you get the polarity right you can replace the AC with DC, the second rectification just becomes a inline diode and the internal regulation has ...

I would start with Morgan Jones

Is there any DC on the output you want to put the buffer stage on?

This'll all be gone soon:

I foresee a problem reaching the upper part of the house...

Just be aware that potting a transformer will affect its power handling capacity as it will be less able to loose heat.

The problem I see with measuring the noise floor and any change is what do you use as a reference?

Just what rating is going to be over? Vds for irfp(9)240 is 200v

I would just get a 18v TX.

Where is it stated that a ground must physically be connected to anything? It's just a circuit reference point. Yes, its necessary to separate how we think about the signal ground from the earth safety ground. They are not always the same thing. But in every case I can think of (other than one that...

Dave sells them, so I should try one sometime.

No, I have no idea what they do. I have considered the idea (but never tried it) of a "active ground". Use a DC coupled power amp with its input referenced to earth with low pass filtering to give a clean ground referenced input, the use the output of the amp to provide the signal ground to the syst...

Yes and no I would say (not that that helps much). Generally, I don't think there is anything for us to worry about as there is nothing we can do about it. Unless of course you are in charge of a server farm, then its a worry, There are politics of course involved as well, as this is a good reason t...

There are both magnetic and non magnetic stainless

I think the point is these circuits are from the time when transistors cost more than transformers and the gaal was a hand held radio that could be powered by two 1.5v cells.

Thanks Nick. I've a lot to learn

Luv, Ami.

Yep, thats whats good about this stuff.
