SSHV2 working hard to tame the high ripple coming from PSU, can't increase the resistor value between the CRC of PSU because I need each volt available, will do with the new transformer.
Does good work. What the Brymen shows if you keep it connected to B+ but you power down the PSU? To see if its mainly general noise the test leads pick.
