Were you the one that bid something like $30.31 for that group of bulbs? Try to
buy new ones. There are many with that same base but not the same voltage.

Not true. I restocked my Rodgers 770 music rack light with new bulbs I ordered
off the Internet just two months ago. They’re not cheap, but they’re certainly
available.

You are correct the old style round glass bulbs were done in series. I suspect
it was something to do with voltage. Btw, those bulbs are no longer available
anywhere. Rodgers had bought out the last remaining stock from GE many years
ago. These bulbs were also the bulbs used in the Lionel Trains.

I think on my 1973 Trio the bulbs are wired in a series/parallel manner. Sets
of 2 bulbs in series that are parallel with other set of 2 bulbs in parallel. I
noticed several times when I replaced one bulb the one next to it would glow.
Strange system.

Correct but keep in mind if they used a higher voltage bulb on the pedal and
melted the wiring oops! Regarding the music rack, look for that dimmer, either
up by the keyboards or under the keyboards. Lots of organists turned them down
to save on the bulbs.

Mike,
I missed the reply you first made. This makes perfect sense. If the organ
functions/plays normally then I do not see it to be a power supply emergency at
this point.
To be on the safe side if replacing the lamps with the correct bulbs does not
repair the problem, the power supply DC voltages should be checked by someone
knowledgeable of the technology.

His pedal bulbs are out, I told him to check to see if they were burned out,
they are the old type car bulbs and folks put higher wattage than they should
at times. I told him to check to see if connections were melted. Also his music
rack lights are dim, told him to check for a dimmer switch and or bad grounds.

You should be able to measure the DC voltages from the terminal strips where
the cabling attaches to the power supply pwbs. If any of those voltages are
greatly below spec then the complete chassis would have to be disconnected and
removed for further testing/repairs done.
What are the problems/symptoms?

Can the transformer be removed for testing without removing the entire power
supply chassis?
Thank you
