Alright, heres what i've been able to measure.

I measured between the valve pin and ground with the exception of the EZ80 anode which was measured between the anode and centre tap of the transformer so its in range of my meter.

V7 (EZ80):
Cathode: 298vdc
heater: 4.9ac
Anode (a): 283ac (to centre tap)
Anode (a"): 283ac (to centre tap)

V6 (ECC82):
Anode (a"): 0v (tested for both ac and dc. nothing at all)
heater: 3.3vac
Anode(a): 0v
Grid(g") 0.34vdc
Grid(g) 0.33vdc

The voltages on the EZ80 seem okay to me.

Looks like it could be something in the oscillator circuit. It's unlikely to be the valve itself since its a NOS phillips but I wont rule that out. I'm getting some more valves in stock soon and one of them is indeed an Ecc82. Might try substituting them.

I'm a little worried about testing the grid coupling capacitors because of their fragility.

Its also worth pointing out that the anode voltages of the EZ80 went up to around 350v but then started to drop and then rested at 298. I'm assuming thats normal as the other valves start to warm up and thus introduce a load?

Any ideas on where to go from here?
