Hello all,
As impressed as I was from the subjective performance of my recent low voltage shunts for my NJFET RIAA (link), I developed high voltage ones for my tube gear too. The first test has been done powering the Steve Bench cascode 12AY7 parallel & 6DJ8 RIAA. A phono circuit is the most sensitive one so to fully test a reg PSU IMHO. The previous reg was a Mosfet Maida. In brief: 1. Lower noise than with the Maida, in CDP background silence territory now. 2. Bass definition and slam, image focus, image size, mid and high smoothness, one class higher with the Mosfet shunt. Maybe a 25% overall subjective performance lift above the Mosfet Maida.
Read the high voltage safety sticky thread if not familiar with tubes and tube supplies practices. A useful reminder for experts even:
Safety practices for high voltage
Updates not to search in a long thread:
SSHV1 Standard
SSHV2
