I am going to overhaul the capacitors of my Yamaha Electone E45's power supply to extend its life. The only problems is that for the 38 volt regulator, it needs 2 55 volt 10000uf Capacitors. The store only had the same uf value in 50 volts.
I did some research and it says you needs to calculate an extra 20% of the voltage in case of surges. I got 38 * 0.2 = 7.6, 38 + 7.6 = 45.6.
50 volts is higher than 45, but is that safe or would it end up blowing a fuse, bursting one of the capacitors or worse?
Schematic for Power supply is attached below.
