Higher rail voltage on ZEN4

PTsomokos · 2nd April 2011, 01:07 PM

Hi there.
I need your advise please.
I'm trying to rebuild my zen4 after 10 years.
I'm going to use a better trafo than the older one with 2x22 + 2x22 (500VA)
This going to be 2x22 = 44 x 1,4 (rectifier) = 60V per channel.
What do i have to change to get 42v after regulation

Another thing that i will try for now is NOT to use the R1 (1R) in parallel with R0 (.47Ω) to get less dissipation. Mr Pass says that i have to change the R16 1.5k to 1k to do this. ok. There will be not a conflict with my new rails (or not).

I'm holding my breath to hearing from you, he he.
Thanks

You won't have to change anything to get your 42V after regulation.

Good luck.
