Default Re: Newb Stumped on a Derwent

Hi guys,

well checked again, and as follows cheers vinrads for the guide to pins.

pin 1, 0 reading nothing (heater)
pin 2, about 25 (anode)
pin 3, 310 (Grid 2, screen grid)
pin 4, 340 (grid 1,control grid)
pin 5, 0 reading nothing (cathode)
pin 6, 30 (dc) (heater)

Guys weird thing hear.... I accidently set the avo 7 to read ac, with the ac dial set to 10 range touch pin 6 with the probe and wow station heard loud albeit a bit a tad distorted this can be trimmed better with the tone. If I change the range up to 100 signal goes.

I'm getting tired and confused and not sure why i'm getting no reading on pins 1 and 5 and why the above would happen, should have stuck to clocks. feel the need for a

is it to do with resistance............. blurt!
