I'm somewhat of a newbie to the world of DIY and need some suggestions with a Royer mic mod/power supply. (it's the mxl 2001 mod with the 5840 tube) I used some pdf's (uploaded by the good folks at the DIY factory) to create my pcb's, but it seems that I've gone wrong somewhere.
Having finished the power supply, I'm getting 77.9 vac from my B+ connection and 25.8 vac from the heater connection.... which should be 95v and 6v respectively. And I don't seem to have any wiring errors. Any help with troubleshooting would be greatly appreciated!!
