Hi,

I have a NOS 8094A - it has about 2 hours on the clock, and today, just
after powering it off, there was a plume of smoke from the back and a
lot of "hissing". dead capacitor, I say to myself...

had a GOOD look inside. With a magnifying lamp. Nothing, except...

....there is a tarry deposit that smells the same as the smoke did round
the back of the main inlet IEC filter and a few spatterings of same on
the inside of the top cover above the filter and to the right (looking
from the back). I suspect, that for the first time in my career, I've a
mains filter failure...

However, a) its rivetted to the back plate (no real problem), and b) I
have no spares part number for it, and c) its a sealed unit, and this a
module replacement...

Is this a known failure mode for these units? Where could I get a spare
filter?

I should point out that it still powers up ok, but I'm understandably
not happy with it until the filter is replaced.

Any help appreciated...

Many thanks
