Hi Frank and techies,
I don't see what this has to do with 3 phase power but here goes. Bob
mentioned the mains voltage but not the rating of the lamps in question.
It just could be they're rated at the old 220V standard (and he did say
it's a European organ so one may assume they're European lamps) and are
operating above the rating. A CV transformer won't solve the problem
because it's output is that of the standard nominal voltage which is 115
or 230V depending on whether it's American or European. It MAY help a bit
by removing spikes and surges but not the overvoltage problem. That's
where a couple of wire wound power resistors come in handy, just knock of
a few volts, a slight undervoltage will prolong the rated life of the
lamps.
Are you reading this Bob?
BTW, I have a 500W CV transformer kicking around the output of which is
120V because it was made during the short time that was the US standard.
It never caught on, most systems including the NE Grid have always been
115-117 nominal. No nit picking guys, I remember before there was a grid
and my mains voltage was 110, the standard at the time.
