Hi Gabe001

I did hook up a scope and there is around 100m/v of signal from the oscillator, I am suspecting that either the EF39 is going down as the set warms up or the triode section of the ECH35 is going down. But when the sound has dropped, placing a finger on the grid of the EF39 will bring up the sound. Peculiar fault this, I will get there in the end.
