I recently built a Fender 5E3 circuit in an old PA chassis salvaging and reusing the power and output transformers. I found a schematic on the internet showing “typical voltages” in the 5E3 amp. I’ve attached the document showing the typical voltages along with the Fender schematic. I don’t know how accurate the document is as compared to other 5E3 circuits, I’m assuming it’s a good target. When I started my amp up, the B+ voltages were much higher than what is shown in the “typical voltages” document. The original PA had three 12AX7’s and two 6V6 and a 5Y3 rectifier. The 5E3 circuit has a 12AY7, a 12AX7, two 6V6 and a 5Y3 rectifier. I’m assuming my voltages were higher because of the output was designed for a different circuit with more tubes. I’ve been increasing the value of the voltage dropping resistors to reduce the voltages in the circuit. The initial resistor in the 5E3 schematic is a 5,000 ohms. I’ve been changing the resistors and doing calculations to find the right combination. Would 10% plus or minus to the typical voltages document be a good goal? Also, do the voltage have anything to do with the headroom?
