i found a carbon resistor in the power supply that is a 3.3 k but tested at 40.5 k so i changed it dont know if it will make much difference. the +140 is low and the +270 is at 258v the difference between 258v and 270v is 12v and if that 12v is put to what i have on the +140 line at most its been was 120-125v seems to make up the loss on the +140. so is this 270v source used to boost up the +140 because the 270v comes in and goes threw a resistor just at the audio tube along with the +140v. what im not getting here is both 41 and 45 series schematics have the same setup in the power supply, resistors, so from the output of what looks like x2 it goes to a 1250 ohm 18watt resistor and pulls it down to what looks like supposed to be 270v but i only have 258v so this would suggest that 18 watt is bad so ill have to lift a leg and check. but checking it in the circuit its up around 1330 ohms. would this little bit pull it down to 258v from 270v ?
