Being Italian I most probably do.

Which in a way is baad as one can't get the proper stuff Like white trufles fresh porcini or even simple radichio.

When I mannage to go back on hols suit case is full of proper stuff like 12 year old Parmiggiano and (quite funni once) 500 g of Origano.

yes 10 K and 200k
on the bench so poor screening and crapy scope as you probably recognise altrought with english name.

Gona run lot on secret PC with Virtinis and Audiophile 192 if I get the time and can bear to take it of FiFi chain, that is going to be hard part from look of it

Now shunty is another story

Hi!ZM in fact, I am referring to the two psu (mine is dual mono) on my old bosoz.
I think I'll have to short some 9.1V zener diodes to obtain the correct voltage.

well , possible , if you stack them and use mid point as audio gnd

of course , for that you need that each PSU have separate , dedicated , secondary

in any case - they can serve only as pre-regs for Shunty's , in which case own Shunty's series ref pre-reg can be cofigured as cap multiplier ........ in which case you'll have overkill on overkill
