Just one more question:

In J.C. Verdier's design he calls for the use of 1 cap after the regulation which he claimed to be sufficient in suppressing almost all the hums and buzz without the need to resort to "pi" filters again.Is that true?

If so would you recommend my use of SState rectifiers (with caps of course) --> 10Watt 50ohm (I'm actually planning on bypassing it with a 3K resistor coupled with a 30sec. time delay switch, as to short the resistor when the time is up) --> regulator (valve/FET, haven't decided yet) --> PSU filtering caps? (initially calls for Cerafines but if my internal space permits I'll probably stick in some Solens 47mfd for the time being .Will 47mfd enough you think??)

Or do you prefer the addition of an additional filtering foil cap before regulator?

Kind regards,
