Hi there. Has anyone got experience of a 4400 with drifting FM? You turn the amp on and then the FM channel with or without AFC is fine gor a few mins. Then it just drifts ho a ranfom station and keeps on doing that. Any ideas and sho could best fix this gor me pls? Tx

Most likely an oxidized trimmer, either the one next to the S-meter or the one on the piggyback tuner board.
But check the tuning voltage for drifting.
This will also help you tell if the drift comes from the power supply that provides the tuning voltage, the trimmer(s)
or something inside the frontend module.

Thanks Martin. Is this something that you could check and fix for me as I wont have the expertise to do it myself. If so, would you charge anything and can I arrange to courier the item to you and pay for the postage back? You can send me a PM if you like. Tx
