Thanks for everyones input ,certainly some food for thought there. I am inclined to go down the motor run capacitor route using a 2.5uf capacitor with a o.33 uf
x2 capacitor in parallel. with a ,2w 50 ohm surge limiter resistor and a 100k 1w discharge resistor ,this in theory would give me 72.6v @ 0.2amps.which goes to pin 7 on v5, the start of the heater chain . but this is where i`m slightly puzzled , on the original dropper there are 2 taps ,the top one for the heaters and another feed to the 150 ohm (r19) surge limiter and then on to the rectifier valve supply,
as this isn`t the full 240v how do i reconcile this or am i missing something ?
all advice appreciated ,
regards, tim
