I find that circuit interesting, Mike.
Many of the resistor values are odd by modern standards - 230, 400, 50k and 70k, for example but we can see the beginnings of the transition to the logarithmic series we are all familiar with today, with values such as 22k and 120k.
And have you noticed the the valve base diagram for the 1807 looks like a very sad face?
Anyway, an excellent restoration - as always.
