Can anyone suggest how to cure the sound going muffled, then clear, then muffled and so on throughout projecting literally any film on this machine please? It's literally one second of clear sound, followed by one second of muffled sound in an on-going way throughout!

Sounds like a tracking issue as the mag stripe passes the head as though you hace intermittant misalignment from a worn capstan roller or guide perhaps or worn pressure pads underneath the head maybe.

Does the film show any signs of lateral movement on entering or exiting the sound head section? For that matter even unusual vertical movement around the lower loop before entering the sound head section?

Have got clear sound if I pull, by hand, the lower plate on the sound head, which pushes the film up, towards myself. Must be alignment then? I will try some other prints.

Could it be that the heads are just worn? Don't sound heads have a life span of a certain amount of hours before they're no good anymore?
