WAD Psu3 replacement Board Build
Hi all
l now have the new replacement PSU and full manual ready to go soon Some questions thought to start with 1. The no-load Voltage for PSU3 at C1 is 410v and on PSU2 its 363vat C1 with same TX 0v-270 volts 60mA assuming main voltage difference seems odd to me 2. Change out the 1k R4 for 22k add the 200-volt Zenner and C3 100uf for the CF pre-HT 200volts 3. add back in C4. 100uf for phono HT 250 volts as was before on the psu2. I was just going to swap over the component to the new board but with the higher voltage the main 100uf Caps are only rated for 400 volts so decided to just use all new parts with the exception of the two bridge rectifiers as they were upgraded off the PSU2 when we build it last time For know thank all Colin
