The do here http://tomanek.net.pl/tomanek-liniowy-z ... wieku.html an Auralic LPSU For 800 Zloty (about 160 GBP)

Tomanek specialise in making high-quality transformers for audiophile use and the unit I have works perfectly.

You can email them for more info.

Its not hard to make a good linear power supply. Once again because it has become *a market* the complications and the bullshit associated with them is appearing. FFS a linear power supply is a transformer (more VA the better) a rectifier circuit, a simple high current bridge is more than adequate, and some capacitance (different arguments for how much) and maybe some bypasses. IT IS THAT SIMPLE it is not rocket science.

EDIT - and the option of a regulator circuit, which is a simple unity gain amplifier, simplest form LM317 and if split rail plus LM337, though you can complicate this if you want until the cows come home.

Check out at www.tomanek.net.pl
Actually I did enquire - and their mini version of their higher end PSU looks good enough (perhaps you can double check for me) - this was their response...

If you want to make your own linear power supply then you could use a LT1083 module from Ebay as the rectifier and regulator.

I've used this one on several projects, cheap enough but have to wait some weeks for delivery.
