I will at some stage get around to revisiting the PSUs in my two * 'Once Were' LEAK Stereo 20s which have high storage PSUs. I will be looking at putting in chokes and PP filter caps. CLCLCC or LCLCC if that's sensible, and get rid of the Rs that are there now except for one bleeder R, IF my techie insists on one.And, I will put Schottkys in to replace the (R&C) snubbed SR diodes that went in in the 1990s. They certainly are measurably and audibly quieter than anything else around.
For me, the limits that valve rectifiers impose on the amount of energy a PSU can store make them unnecessary.
The hole where the GZ34 was in the LEAKs now holds a 470uf 400V, dark brown, low ESR Nichicon cap. One of 4 per chassis.
The very positive effects on bass sound quality and headroom from a high storage PSU applies to all amplifiers.
