Wurlitzer Organ repair help

Wurlitzer Organ repair help

2007-06-25 by Kate

I could use some suggestions to repair my Wurlitzer Model 4373. I 
inherited it from my Uncle recently. It appears that it had not been 
played in quite a while, as a lot of the keys made no sound and there 
was a lot of static in the switches. I cleaned all the contacts which 
restored all the keys and eliminated the static, but the pedals do not 
work right.
Going UP the scale, I press the pedals:
   C D E F G A B C
The sounds, however, come out
   C D E E G G B C
When I play the pedals DOWN scale, neither the E nor the G play any 
sound...I must go back up the scale to get the sound (albeit the wrong 
notes)
I cleaned the contacts, made sure there were no obvious shorts or 
crushed wiring, but no luck.
Anyone have any suggestions?
Thanks for reading this far...
Bob

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.

These organs used only a single contact for the pedals. It sounds like you
may have a circuitry problem on the pedal board. If the contacts are bent
and not opening properly, you may have a similar problem because they are
low note preference. Thus going up, the lowest not would sound on a bad
pedal, but going down, the bad pedal would be silent. I would bet it's the
pedal keyer ic causing the problem. If you are not familiar with the
circuitry, either go to the MITAtech website and find the name of the
closest tech to you, or contact Morelock. You can order a service manual to
get started. Hope this helps.

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 .

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.

Re: Wurlitzer Organ repair help

2007-07-01 by Kate

Thank you all very much for taking time to respond.
I checked all the plastic sticks that activate the contacts, they are 
all in place. I cleaned the contacts with non-lubricating cleaner and 
a piece of heavy paper soaked in cleaner to make sure the conacts 
were clean. I traced the wires through the organ and could see no 
obvious signs of damage anywhere. The F pedal plays an E note; I 
tried putting a piece of paper between the contacts of the E 
pedal...the F pedal still plays an E.
Any more suggestions?

Bob

RE: [vintagesynthrepair] Re: Wurlitzer Organ repair help

Call Morelocks and get a service manual to start. If you are familiar with
tracing circuitry, then you can probably find the problem. I am betting on a
problem in the pedal keyer ic on the pedal board or some chewed and shorted
wired. If you are not comfortable with going any further, then go to
www.mitatechs.com and look at the membership list for a tech close to you.
The ic is a 40 pin large LSI ic and sensitive to static.

Thank you all very much for taking time to respond.
I checked all the plastic sticks that activate the contacts, they are 
all in place. I cleaned the contacts with non-lubricating cleaner and 
a piece of heavy paper soaked in cleaner to make sure the conacts 
were clean. I traced the wires through the organ and could see no 
obvious signs of damage anywhere. The F pedal plays an E note; I 
tried putting a piece of paper between the contacts of the E 
pedal...the F pedal still plays an E.
Any more suggestions?

Bob
