The filament string dropping resistor R59 was a 41 ohm 20W is now a 60 ohm 25W resistor that runs very hot. My spit sizzled when applied with a craft stick. Do they always run that hot? Do I need to go with a larger wattage? I went to 60 ohms because my line voltage is 122vac.
Looking good!
Perhaps use a diode dropper for the heaters? 122v times 0.707 equals 86.25 volts... close enough to 88?
