ST-35 PSU

Hi all,
I note the PSU mod in the Rev E docs. Is it worth doing with my Rev D amp. I have a GZ34 + choke + 33uF first cap. I assume I could jumper R32 and change R33 TO 6K6.

I think that would be fine. As far as inrush current and your GZ34, I think the CL90 and DCR of the choke will both help out to keep it safe. Probably. ;)

Thanks Shannon.
Has anyone modelled a GZ34-choke PSU for this amp? -just out of curiosity.
