Hi All,

I'm attempting to repair a high end DCC recorder (Philips DCC900), the
fault only seems to affect DCC tapes not normal cassettes...

On playback there is a high pitched howl, suprisingly load from the
transport mechanism, loading the capstan flywheel (with my finger, to
slow it down) didn't make much difference, pulling the rubber pich
roller away also made no difference.

When the transport is howling the audio level goes to zero.

For a while, the sequence of rewind, stop, play - howl, if followed by
a stop and play then the howl went away.

This doesn't happen when the cassete is removed or using a regular
cassette, different DCC tapes also howl.

If I press the tape lightly while playing in one corner the howling stops.

All help welcome, I'm trying to sort this out for an elderly neighbour
who has a large collection of DCC tapes.

TIA!
Paul

Sounds like bad bearnings.
