I used a chassis I had to hand, but have followed the layout in the Sterns construction manual carefully.

The 10M grid leak resistor is there.

The OPT connections are temporarily quite long. Could that be an issue? I also need to get a 560 K cathode resistor for the EL 84.

Can I view the oscillation on my scope?
