Baldwin C630 octave divider ic

[Powell Gordon]

I’m working on a c630 and want to verify the octave divider chip. It was worked on previously and not sure what was done to it. The installed divider chip is a M083B1.

Not sure this will be of much help. I have a C630T, which has a very different frequency divider design with 12 ICs across 3 boards. They are all SAJ110. I do have the manual, and it shows only the Baldwin part no. for the single divider chip used in the C630 as A-514-047801. A contact that may be able to cross-match it is Robert Spoon, 508 Driftwood Lane, Rogers, AR 72756; 479-876-4601; 479-270-2678 cell.

Back in 2001 I ordered several MO83 TOS chips from Organ Service Corporation. I don't know if they still are in operation, though. Those chips were used in the single-board Tone Generator for the later-model Schober Recital Model instruments.

This organ has a single chip and oscillator. I can't find a schematic or service manual for it and didn't want to get to deep into it until I verified the Octave divider chip. Sounds like the M083 is the correct part. Thanks for the help. Any ideas on where to find one will be greatly appreciated.
