Re: Wartime civilian receiver what to replace Westector with ??
Apologies for the confusion.
After studying it further I realise the Westector is forward biased.
Although it has +8.6V on the cathode, the Anode is +12.6V.
If I take the 47k and 330k series resistors into account, the forward bias current seems to be about 10 microAmps.
That should be no problem for an OA70.
