I am not sure I understand the fault description. In particular, what
sort of noise (hum, chattering relay?). And what do you mean by 'trigger
off'. Do you mean the contactor drops out, or the breaker trips, or what?
Let me know exactly what happens and I might be able to help.

Hi Mike,
I have an old 861C (and a 874A) which are very noisy and trigger off
after a short period under load. Would you, by chance, have a copy of
the schematics?
Or matter of fact any knowledge as to the cause of noise(old capacitors?
...).
Your best bet wouls be to post to Classiccmp Classiccmp mailing list at
cctalk at classiccmp.org.
