Default Re: Tandberg Huldra 8 valve failure

Ah hold on, looking at the circuit it would seem that I have described how the EM87 gets its signal on AM!

It looks indeed as though the EM87 gets its signal from the output of the discriminator on FM so yes, I cannot see how it is working with a dead EF89.

Cheers
