Hi All,
I'm fixing a Fostex 280 cassette recorder. It had a broken (melted) belt which I replaced and gummed up supply and takeup bearings, which I cleaned and lubricated.
When I record a test tone into it, it records, but along with the tone is a rhythmic chirping, it sort of has a galloping rhythm. It is on all 4 tracks. When I record without an input no chirping. If I record with the pitch control all the way up and playback at that same speed, the chirping is a faster rhythm but the same pitch.
What is going on? It seems particularly odd that it doesn't record without an input.
