Hi.
The circuit doesn't seem to require any adjustment to the feedback, going too low on HT volts and it just stops, go above 110 v and the audio gets very distorted.
Hand capacitance is a big problem so I use a plastic knitting needle to keep me away when tuning. You can add a loosely coupled single turn coil adjacent to L2 at one end to improve reception with it connected to a dipole. Station Separation is not an issue and it pulls in very weak FM stations with ease.
Two disadvantages are, 1.... I'd not say by any means this is hi fi, it is a little distorted on reasonable signals and worse with strong ones. 2..... These super Regen receivers radiate and for a fair distance, Ideally you need an RF stage for isolation.
It may work better in a tobacco tin for screening and reducing hand capacitance.
HT current is between 0.95 and 1.1ma dependent on HT volts.
Have fun.
