Hmm - have a couple of smps +-45Vdc laying around. Will try them. Still waiting for parts so I can start soldering.


Not sure if it has been said before. What is the PSRR of the V4H modules?

Sincerely

PSRR hasn't been measured for v4/v4h. However as I can't hear any hum with only 10000uF in the rails I guess PSRR is high enough for a dark background.

Hi Shaan,

Happy to report that I received my PCB's last week.
A question in regards to the heatsink requirements: do you think an SK 85 75 SA heatsink is sufficient for one channel?
This heatsink has a thermal resistance of 0,45 K/W.

Yes, have complete parts for 4 channels. But only need 2
Would it be any benefits if making it complete balanced or should I just make 2 amps?

Thinking.....
