When you get back to the heads issue, what might be a useful test (with a reel of blank or unwanted tape) would be to set the machine running on replay, and to bring your defluxer close to the head gap. Even with tape running over the head, the field of the defluxer should get through the gap to the gap and give you a hum. That running test should eliminate the possibility of head-switching issues killing the signal.

Mike from post 158 I did the head demagnetiser test of both heads individually in Forward and Reverse Play getting loud hum for the respective head, this was done without tape, I don't think doing it with tape would make any difference to the results.
