I emailed Yamaha and they replied that the CVP-50 is too old–no replacement available through them. The Yamaha site lists only two CVP sliders still in stock. I am attempting to replace the volume slider on a Clavinola CVP-50. There is only one volume slider.
The service manual states, If the user points outs defective volume control or if a complaint is received about interrupted or clamorous sound reproduction while adjusting the volume, please replace the slide volume control with the new one.*
This Clavinola, serial number 009148, exhibits such interrupted and clamorous sound production. It possesses the original volume slider but the only marking on it is 9384-10KAx2 which does not correspond to anything on the Yamaha parts site. The slider is 45mm long with a stroke (distance the actual slider travels?) just slightly less than 45mm. Facing the open top of the Clavinola with the circuits exposed, my slider has 4 soldered electronic connects on the left, and two on the right. It is a single slider with no clicks. There is one on the Yamaha parts that is the correct impedance and connections are the same, part number VF933700 which was replaced with VK36900R but the stroke is only 30mm which is probably too short? Otherwise solder connections are identical.
Any idea if one of the sliders on this website might be a suitable replacement?
