Very sorry! I forgot made this post (someone over at alt.digital.tv
remined me). I want to test for faulty caps. It's in a power supply
unit in a 1980's professional multi-track tape recorder


Faulty capacitors in power supplies usually make themselves apparent by such
problems as low voltage or excessive ripple on one or more of the output
lines, or rather more obviously by leaking electrolyte, bulging seals etc.
In view of the age of this unit your best bet is probably simply to replace
any suspect capacitors rather than bothering to try and test them.
