Original MM5823N / MM5823 Divider IC Chip – Tested Working

Description

Obsolete MM5823N Divider IC chips used in many Moogs and other vintage synthesizers & organs.   If multiple keys of the same note are out it’s likely due to a divider IC chip.  This chip is used and was desoldered and then tested working.  Photo is of a representative chip, markings and date codes will vary.

Number of these chips per synthesizer:

• Moog Liberation – 6
• Moog MG-1 – 3
• Moog Polymoog – 24
• Lowrey C500 Celebration – 12
• Lowrey TGS Symphonic Holiday – 12

I also make the SC5823N, a new replacement module for the original IC chip.
