An AM/FM prewar set, this one by Emerson.


Except for the AM/FM set, all these below Emerson tube
radios use the same circuit board. This board has the IF
tube input biased to ground instead of the AVC line. The 708s
above, though a point to point wired chassis, did this too. Thus there
is no point in using a remote cutoff pentode (12BA6) for the IF
stage as its gain is not varied. So I replaced the 12BA6s with
some 12AU6s (sharp cutoff pentode) I had many of. This reduces
"modulation rise" distortion products in the amplified signal.
