Maybe a divider with two resistors could be used

A small trimpot (1K to 5K would do) connected from the speaker secondary of the audio output transformer to ground, the tap feeding the yellow wire connection back to the existing volume control should work. When you have the set on, twiddle the pot to get pleasing amount of feedback. If it oscillates, exchange the output transformer secondary wires hot and ground, to reverse the phasing (or if it's easier, the primary wires' connections plate and B+, but do not do both primary and secondary!).
