No Allan, if I tune the coil core it cuts out in a different place on the dial. Also I have checked the VC on the bridge and it is smooth from low to high, I also checked the other 3 gangs and they are identical. The grounding connections are all perfect.

No Lawrence, I have tried both metal oxide and carbon composition, no change.
Remember the other 3 low bands are perfect, it is only the 3 bands that use the nylon type formers that are the problem.
Winding a new coil on a new former is my next job.
John.
