I have one of these old timers and the bar sweep and color sweep

Anyway, I have the full owner's manual that includes maintenance and

Does anyone have a schematic of the 500 generator board and parts
layout for the same board?Â* This is the only board where the component
legends are not silk screened on the board, and there are at least 12
ICs - all 16 pins each, most of them the same number.
You might try asking on the forum.

Oh, I found a post asking for the VA48 schematic.
