Default Re: Philips EL3542 tape recorder problem

The discussion so far has covered the usual bases. There is one thing
that I remember about the EL 3542 A from the past.

The automatic stop circuit derives voltage to work the metallic
leader relay from the cathode of output tube.

This voltage charges a capacitor which discharges into a relay,
which in turn applies a high voltage to the release magnet.

Check that assembly thoroughly . If worn, dirty, or arcing,
it may throw noise.
