FA : Leslie 122A Speaker for Hammond Organ
VOTT
Larry
I'm a Leslie dealer in Charleston, SC, and repair organs for over 15
years. This Leslie has bad drive motors in it with defective bearings
that Hammond-Suzuki forgot to lubricate when it came out. They
ignore, generally, the problem. The sleeve bearings are way too soft
for the pressure the belts put on them so will wear out very rapidly,
even if you oil them regularly.
Hammond-Suzuki has a NEW, direct-replacement motor for them that has
ROLLER BEARINGS in them that won't wear out in our lifetime. Contact
any Hammond dealer and get them replaced BEFORE the optical speed
encoder crashes into the sensor, destroying the interface board and
paddle wheel which Hammond-Suzuki thinks are NASA space station parts
and are priced accordingly. Each motor is around $90 for the new
ones.
Replacement is very easy....Just take off the encoder wheel and save
the screw parts. Remove the encoder and BE SURE TO NOTE WHICH WAY IT
PLUGS IN! It can be plugged in backwards which is bad. Unplug the AC
leads off the motor windings. Reverse it and put in the new motors.
It's an easy job...
If this unit ever blows a fuse for no apparent reason, replace the
Triacs, both of them at once, in the heat sinks on the motor control
board inside the bass speaker baffle. One side of a triac will open,
making the triac a rectifier. AC motors draw LOTS of current and HUM
LOUDLY when half the triac is open! This blows the fuse. Replace the
triacs with different triacs.....more than 800V PIV and 6A Ic triacs
work great. www.mouser.com has them real cheap......
The switching makes the motor windings kick and destroys the original
ones, sometimes......
Nice looking speaker cabinet. Too bad someone scraped it around the
top. Tell the bidder after the check clears...(c;

Extremely intelligent life must exist in the universe.
You can tell because they never tried to contact us.
