"I thought it was about time i made a video for this Jen Piano 73 electronic piano which i've had for quite a while. I completely fluked finding this by searching nearest first one ebay, it was about half a mile from my house in a converted old school house in front of the primary school i attended as a kid!
Jen are better known for their sx1000 synth and their organs so this keyboard has some stop switches in a similar vein to their organs. These are just for switching on and off fixed passive filters but can still give a fair bit of variation to the sound. There is a glorious sounding phaser built in and a fixed rate vibrato. It has 1/4" pedal, external out and headphone sockets on the rear.
It also came with a full schematic which shows that every single key has its own fixed envelope! They are adjusted in clusters so that the higher notes decay faster than the lower ones. The voicing is based on organ technology with top octave synths (oscillators) and dividers so it never runs out of polyphony which is nice. The keyboard has quite a nice action but because there is no velocity it can be very easy to catch a bum note. That's my excuse anyway.
I've uploaded the schematic here:
