That is one "spiffy" M-3, for sure! The "rear panel" is a Hammond deluxe back assembly, available at extra cost. The permag speaker tells us that this is a later model instrument. I would put that...

Suggest you bite the bullet, give them the model number (400?) and order a service manual from Dave's Electronics, 105A East Penn St., Hoopeston, IL 60942 USA

It looks to me as though apples and oranges are being discussed, here. The 950 first appeared in 1978 and was an I. C. divider organ, while the 4300/4500 came out in 1964, using transistor divider...

Hello, Admin;

I tried to post a "thank you" for getting the new server up and going, but was told I was not allowed to post there.

Why is that?

Thanks for your generous offer, Toodles:

Please send me the IC and I will pass it on to my friend. I will IM you with my postal address.

Regards,

I would like to hear from any of you who have "parted out" a Trio 321A, in order to help a friend who needs the LSI from the RhythMaker auto. rhythm unit.

Thanks!

To correct a misconception from Altivo:
"The Hammond changes, at least on the B3, are easier to do than the Wurlitzer 950. If I recall correctly, you just set rheostats or rotary switches with a...

Mak, have you had a look inside the back? Your problem may be a simple as a "noisy" rotary carbon pot (aka potentiometer) on the Tibia channel. Over time, those controls develop weakness in the wiper...

A South African Gulbransen! Thanks for posting the photos, Peter! It was good seeing the inside of a B, after all these years. It was also known at the factory as an 1100 and was introduced in 1957....

I began accordion at age 12 when my parents were visited by a door-to-door salesman from the Ft. Wayne Music Center. He signed me up and started me in class lessons playing a 12 bass. After several...

The TSO coils are nothing like the Farfisa coils mentioned above and I advise against heating them.

What is the actual model number of your Kimball? The 1500 series covered about 23 different models, built from 1965 through 1975, so we need more precise information.

Euro, tuning the TSO is a "piece of cake". Stores such as Radio Shack carry a set of plastic alignment tools for adjusting the slugs inside the 12 metal cans on the 12 tone generators. There are apps...

Thomas used that system from the earliest model G into some of the early transistor models. Maybe they got a really good deal on pots from Allen-Bradley? Their expression pots sure had their share of...

Hello, Jim;

The TSO-25 was first introduced in 1967 and was a very reliable organ. The tone generator used simple transistor frequency-dividers. I no longer have that service manual for sale from...

Model GP came out in 1957, based on the model G (shared vacuum tube tone generators), then was replaced in 1958 by the GS-1 (same tone generators) with a stereo phono installed.
