Also grid resistors 12 kohm ....to 1 kohm
Both plates are shorted!

Well winter is nearly here and petrol is expensive so I can use it as a heater.........LOL

My rough estimate to drop ~100V with ~80ma current is that you'll need a 1250ohm/35W resistor.

All Your current for both channels is about 160 ma....Power of resistor must be 2-3 time more than counting...Grid res. of EF184 must be 1 kohm.
