Yes, I'm reading it Warren but with your idea of wire wound resistors you
have forgotten something - to use them in this case would be creating a
highly lethal situation unless the resistors were encased so that noone
could put a finger on them when servicing the organ. Electric shock at 250
volts is lethal.
I don't know where the lamps were made, I didn't look but my guess would
be that as with nearly everything we buy these days they would be made in
China! The problem could probably be cured with an auto transormer but
really the pedal lights are not essential and I wouldn't go to that much
trouble. I don't know how tolerant of a lower than normal voltage the
generators in the organ would be.It could cause problems especially as it
is not digital.
BTW - I noticed something strange here a few weeks ago. We had a storm and
the line voltage on my mains dropped to 38 volts (normal 240). The lights
were quite dim, the computer gave up and closed down as did most things
electrical in the house, but the TV set did not turn a hair. It kept going
at full brilliance and with normal sound and picture. Work that one out!It
is analogue by the way.
