E H Scott Allwave 15
#7

I've just taken one of these sets in for restoration. What a behemoth! After re-stuffing all the wee capacitor cans & replacing all out-of-spec resistors, I have the powered it up. The audio & IF sections are all fine but I cannot get the local oscillator to cooperate. Any suggestions? Also the mixer tube in this particular set is a 58, not a 2A7 as the two circuits I have found, show. The circuit of the audio amp is also a bit different. The detector is the full-wave type using both diodes of the 55 valve and the Radio Museum info suggests that this was employed in a later version of the circuit but the 58 mixer would suggest otherwise. I therefore assume that there are other circuits somewhere out there. All very interesting. Michael, does your manual contain a circuit that you could copy for me please?
