[Amps] Alpha 87A was humming along nicely when...

[Dick Green WC1M]

Did you see a hard fault code displayed when the amp was restarted? If not,
you should dump the hard and soft fault tables using the RS-232 interface.
The information there may be helpful.

My guess would be a tube arc, but that's just a guess.
