Hallicrafters S-20R

Yes the 6SJK7 does amplify. The windings I redid don't have resonating capacitors; those are on the secondary.

I don't have a dip meter but will see about measuring resonant frequency.

This unit was almost a basket case. It had rust all over, a warped-beyond-usability bandspread window, no dial strings, burned coils and torn speaker cone and missing knob.

I've got most of the problems resolved but this one is baffling me.

Ask your friend what he has and how much he wants. This radio isn't mine so I have to get the owner to pay for any parts; so far the cost has been zero.
