Gavotte 9 FM tuner problem

 My Gavotte 9 will receive FM signals loud and clear from 100Mhz to 108 Mhz but cuts off at anything below 100Mhz, only low static. Changed ECC85 to no avail, I suspect antenna coupler but has anyone seen this condition before?

Any response appreciated.

 My mistake, sorry to waste time.

The ECC85 that I had substituted had leakage. New tube/valve fixed the problem.

Often complex problems have simple solutions, usually human error!
