Many thanks for the information. I shall be looking at the organ again on
Monday and will report back. I much appreciate the effort you guys have put
in.

Does anyone have Datasheet or the pinouts for an AY1-5051 Fixed Modulus
Divider chip? I can't find them on the internet. It was made by General
Instruments (later Arizona Microchip) and is a PMOS technology.

I am trying to repair a 1960's Elka organ for an 82 year old friend. He
has had it
since nearly new and it has been reliable until now. He would rather
repair than
replace.

TIA
