Hello,
I just acquired a Yamaha YC-45D yesterday. I was informed that the 8' and 4' stops did not work on the Ab (3rd octave on the upper manual), but for $500 I had to buy it. I spent around four hours dusting with my air compressor, cleaning contacts, wiping everything down with a rag, re-dying the black leather exterior, polishing all visible metal/wood, gluing any peeling leather, et cetera, so everything looks great... Unfortunately, the stops still do not work (I didn't really expect cleaning the contacts to help, but I knew it also wouldn't hurt).
Along with the 8' and 4' stops, the 'piano', 'harpsichord', and 'marimba' stops also do not work on the Ab³ key. I can hear what sounds like a 1' muted stop on the marimba setting which leads me to believe that those are just presets of the 8' and 4' stops with some other added effects (bright, vibrato, et cetera).
I pulled all of the circuit board cards out and checked for any obvious signs of blown circuitry. In which I found none. Upon reading the original service manual (found here: http://dl.lojinx.com/analoghell/Yama...viceManual.pdf), I saw that Ab³ was generated by board UE5. That's all I know so far.
Any help on this matter would be greatly appreciated. I'm ready to play this thing!
Regards,
Demeter
