Wurlitzer 1203 Tech Notes & Power Problem
By John A. Tuttle

> Hello John: I recently subscribed to the MMD newsletter.  I have
> had a long-time interest in player pianos and just purchased a
> Wurlitzer model 1203 that has a problem with blowing the main
> power fuse.  I have purchased the diagrams and trouble shot the
> electrical system to a certain degree.
> I find that the motors seem to be okay but the fuse blows when the
> spool switch actuates.  By looking at the diagrams I feel that my
> problem is in the power supply circuit.  I have checked the power
> transformer and it checks good with a meter, however, I have not
> been able to get any voltage readings because of the fuses blowing.
> I am hoping that you will be able to give me a few words of wisdom
> to help me along.
> My background is in aircraft instruments, with about 28 years exper-
> ience from flight line maintenance to depot level repair of the
> actual indicators.  I retired from the USAF in 1977 as a M/Sgt.
> Thank you.

Hi Jerrold,  After some deliberating, I decided it was easier to scan
all of the Wurlitzer 1203 Technical Notes I have and upload them to my
server.  For easy access and viewing, I created a web page and listed
the subject of each note and linked it to the associated image file.
There are eight files and each one is an average of 138 kilobytes.

Each picture can downloaded to your computer by clicking the right
mouse button and selecting 'Save Image As...'.  (Remember where you
saved it).  Then open the file in any graphics or photo album program
and print it out from there.  Be sure to check the printer and page
setups before printing so the printer uses the whole piece of paper.

The tech notes cover the period from 1972-1980.  I am missing notes
No.  1 and No. 4, so if anyone has those notes, please send them to me
and I'll add them to the list.  The web page is located at

If the editors of the MMD would like to put the image files into the
Archives, I'd be happy to send them along.

 [ Thanks for the offer, John.  I'll contact you about details.
