Very sorry! I forgot made this post (someone over at alt.digital.tv

unit in a 1980's professional multi-track tape recorder

Which one?

If an analogue PS a faulty cap would usually just cause hum, etc. If
switch mode you'll really need an ESR metre to check them.

As mentioned in the above post, it's a Saturn Soundcraft 24 track.
