Sudden death in the family :(

Hi all,

Today is a sad day. For obvious reasons, it already was (no, let us NOT
start that topic [again] .. tis a sad day, period), but now it's even
more so.

I just powered up a friend's PDP-11/53, which had been sitting in my
living room for, er, quite a while, and... nada. Fans dont start up,
not the usual racket when one powers up a BA23. The light in the power
switch turns on, though. I can hear a very soft "tick-tick, tick-tick"
sound in the power supply, and I do see how the fans get started, but
very quickly die down. Likewise, I see several LED's very briefly
turn on, and then die off again.

So.. looks like the power supply died on me, just while sitting there.

Is this a "known symptom" with the BA23 power supplies? It's a newer
one, with the colored wires.

If anyone near me has a spare BA23 they'd be willing to part from, or
at least the power supply, that would be heaven... my friend's gonna
have my liver for lunch for nuking his system....

Cheers, sortof,
