Vintage Synth Repair

Sometimes it's hard to remember what happened yesterday. But when you work
on them all the time, it's hard to forget.

Hi John.
We were a Wurlitzer dealer from 1957-mid 80's when they were sold to
Baldwin. I've been a tech since 1968. Pedals have always been low note
preference. The orbit keyboards were hi note preference. But you are correct
about the plastic swizzle stick. It is possible they are either broken or
not in the proper hole in the pedal. Unless the organ has been moved, they
are probably still in there somewhere. I would still look at the circuitry.
Perhaps a mouse chewed some wires and shorted them out for the bad pedals.If
the customer did find any mouse droppings, they should be very careful in
how they remove and clean the offending area.

My Mother was a Wurlitzer dealer in the 60's-70's . If I remember ,the
pedals used a nylon "stick" that ran from the pedal to the contact switch
.They were prone to breaking .Also,the Wurlitzer played only one note at a
time on the pedal board .And play the highest note .

If I remember correctly (it has been a while) that
model Wurlitzer used a key contact that had both a
normally closed part and a normally open part. I used
to clean them with a rather thin rubber tool made by
cutting a strip from a big eraser. The silver plated
bronze contacts get corrosion. There are two wire
contacts with a flexible spring contact between them.

When I was in the trade, I dealt with Mark and his
wife, very nice people. I don't know how much of the
stuff is still available.
