Hello David, What an interesting set there. I enjoy reading about these early 60s portables although I have never repaired one. Looking at the circuit diagram I can't help noticing the 2 valves in the EHT doubler don't appear to have any heater supply from the LOPT. Am I missing something here? Look forward to reading more.

Alan.
