I have Hammond AO44 chassis with a NOS EZ81 and a new filter cap/can (30-30-30-10)
I'm looking at using this for the sparticus mod, but retaining the EZ81 rectifier/power supply. The sparticus mods pwer tube/output section doesn't appear to be that much different than the original, mostof the mods seem more on the front in for extra gain
The sparticus plan eliminates the rectifier tube in favor of 1N4007s adding an upfront 82 ohm resistor with a 100 uf filter cap to simulate the recto tubes internal resistance and affect sound...but without a before after..?)
The totem resistors are the same as the original but the filter cap values are higher (100-50-50-50)
the indicated output voltages are with 2% (original/sparticus)
anyone see a problem with staying with the lower filter values?
