Needed: Download site for Wurlitzer 3500 Zodiac SCHEMATIC

I know it takes many pages to tape together but I've done that before. I
have a manual just ordered from Jeff Wager but client pressure to repair it
for the weekend if possible.

Thanks, Al Last

Most problems with Wurlitzers are bad or noisy microswitches. I
recommend that you test ECRY microswitch with an ohm-meter before
moving on to other potential issues. The other area to check are the
latch switches on the keyboard, clean them with a points file and
adjust to the manual.

Thanks John for the advise. Yes I agree with you on the microsw problems. I
too have repaired many of the 3000 and american series. More than I really
want to admit to. I promised the wife I'd NEVER bring another of that series
in our garage again. Oh well, the things ya do for a buck. I have most of
the 1800-3700 manuals except the diac 3500. It is slightly different credit
accumulator. I already checked and replace about 4 micros last week. I've
adjusted and cleaned the selection panel and relay contacts etc. I need to
check the timing of the sw closures under the keyboard as I think RY2 START
relay isn't getting a chance to lock in fast enough to allow the stepper to
register the XY selection, rotate to it's location, and punch in the pin.

I'm working on it as I write this email so probably have it repaired before
manual arrives from Jeff Wager monday.

Thanks again, Al Last pins4us
