Zenith Chromacolor ii set problems

[Jon A.]

It's an odd setup for sure, an RF bias control on the AGC/sync board and another control simply marked "AGC" on the preset tuning board.

I looked into the home brew coils but chances are the magnet wire would cost as much or more than a ready-made coil. I've already called one for my B-day in a few weeks so problem solved.
