I have one of those and an SA-160. The 160 had a problem with cracked
solder joints on voltage regulator transistors on the main heatsink.
The 160 is a little odd to disassmble and I think the 210 is similar.
Got a digital camera?

Yup.

take lots of pics as you open it up so you can
get it back.

Will do.

You _might_ have a thermally intermittent power regulator
but bad (metal fatigue) solder is far more common.

Not sure when I'll be able to get to it. Too many irons
in the fire ...

So ... find the big heatsink. Voltage regulator is on
this unit? Remove regulator cover to find transistors and
possibly cracked joints??

Much Thanks,
