Yeah, tried fleabay, but not a lot of luck. The main issue is that they are designated as RS451111 series. They need to be 10k B-taper though, mono. Strangely the sliders I have from Yamaha say 10k-B on them (yet their packaging says 100k - humph!). I have metered them and they are 10k!

They are 60mm long with 45 mm track/throw. Also, the prong for the slider knob/cap is very short, like 5mm, whereas just about all the 451111's you find are 15mm high. Thought I would try to get "insulated" ones so I can saw them down to size (harder with the metal ones!).

Underside the connecting prongs are 2 one end and 1 at the other end (ie voltaqe end to end and then the second prong is the slider tap).

As far as I can tell they are only control voltages, so no audio actually passes through the potentiometers.

Looking forward to seeing some pics of your next ventures inside your recorder and your hearing of your source for the sliders.
Will do when I find time and my eyes can focus. Need glasses, lots of light and a magnifier these days - gone are the days of building a synth back in the early 1970's! Oh the joys of resistor chains for the keyboard, military grade resistors and small trimmers for each note as well - and still the little b*****s don't stay I tune - but they did have character!!!!
