Carefully removed from a vintage Yamaha YP40 Electric Piano/Clavinova - this assembly is now offered to restore other Yamaha YP40's
Yamaha Electric Piano/Clavinova SPARE PART
Sub Audio Control Board
Part # AN 1623 LC33101
Made in Japan
Primarily is populated with multiple JRC 4558 op amps, a couple of 4000 series logic (4069/4016) and a IG10090 (16 pin DIL) but I am unaware of its function.
COSMETIC CONDITION:
Very good condition, no damage to the PCB at all
No damage to the original connecting connectors.
No soldering is required to fit/replace this board, plug and play!
TESTING:
This PCB is fully functional and without any issues at all.
It was removed from the vintage YP40 because the "E" finger on the keyboard was mechanically damaged. This was the only thing wrong with the YP40 but there was no interest in the complete instrument with one key not functioning!
Since removal from the instrument, this PCB assembly is now stored within sealed plastic to protect the components and connector contacts from dust and contamination.
