I agree with you 100% Sam.

The fact that the EF89 lights up and its presence or absence affects the observed behaviour of the set indicates that it has power applied to its heater.

However the OP has been unable to measure any voltage on the heater pins and I don't think he has tried to do so since being requested to check this again. This gives me no faith at all in any future readings the OP posts, especially where the reported voltage is zero.

I have done my best to help the OP, but little progress has been made since post #87.

Time for me to retire to the side lines and let fresh minds handle this one.
