video by Rustboy
"A non-scientific comparison of four System-8 filters :-)
1. System-8 standard LPF/HPF filter
2. System-1 filter
3. Jupiter-8 filter
4. Juno-106 filter
You can check official Roland's introduction for other examples." [posted here]

Looks like the same one listed here from another seller, based on the serial number, missing screw, and description? Different pics though. One is priced at $22,900 and one at $22,950.
Pics for that one captured on the 21st here.
"The Jupiter-8, or JP-8, eight-voice introduced by in early 1981
Item is in Excellent condition with a few minor scratches, you can see them in photos. in FULL Working order, every knob, electronics, sliders, everything works perfectly."

"This Korg FK-3 Guitar/Synthesizer Volume Pedal 1980s is in great condition overall for a pre owned item. This foot pedal was tested by a professional player and was given a clean bill of health. It is in the cosmetic condition shown, so please see all pics. There may be marks, scratches and scuffs here and there from age and use, but still very respectable (see pics)."

Vintage Saarang Electronic Tambura Tanpura Drone Synth Synthesizer Radel TBR 8
Note: Auction links are affiliate links for which the site may be compensated.
via this auction
Runs on 6 C batteries and for having such a small speaker can get loud, it also has a 1/8' mono speaker outlet on the side. Radel Saarang Electronic Tanbura
The 'Saarang' produces the plucked sound of a conventional stringed tambura (tanpura) used for classical Indian music. The sound is produced electronically without the use of any strings. The 'Saarang' plays by itself and does not need a person to play it, you just adjust pitches and speed.
Pitch tunable by more than octave and covers the range of male as well as female voices - from lower A to higher C (lower 6 to higher 1, Karnatic system or lower White 6 to higher White 7, Hindustani System).

Product sheet scan below.
"Here is a very sought after vintage musical device: The Simmons Clap Trap with Humanizer function. It is the last of the analog versions of the Clap Traps before they went digital. It is an analog handclap synthesizer with controls that allows you to shape the handclap sound from a thin click to an almost drum slamming sound, and play them back on the unit. It also provides different trigger inputs in the back and the ability to alter the sensitivity of the trigger signal. This unit was used on such 80s hits as Gary Newman's CARS and Kim Carnes' BETTY DAVIS EYES."

Handmade DIY Synth - Sound/Noise Generator 5 oscillators madness with CV in

"This is a Synth/Noise Generator/Toy/Portal I built completely from scratch. The circuit I designed starts from basic schematics you can find in the datasheet of the main sound generator IC (40106 and 4046). The ways the oscillator interact are based on almost random routing and wiring, going through several logic gates, including a 4066 if I remember well, for automatic switching.
There are 2 LDR, although the video don't make much justice to their function. If on certain setting, it will produce different sound at night rather than during the daytime. You can experiment pointing a torch to the LDR or to bend over them to modulate the sound (it affects the behaviour of two oscillators, in ifferent configurations).
There is also a nice area with bolts sticking out. If you touch two of them, particularly after licing your fingers, you can dramatically control the sound.
There are switches that controls the routing of the oscillators or enable larger capacitors, LEDs to make it funky, and some sort of CVin (minijack). I played a bit with conductive dough I made with my son, but it would be cool to try it with veggies and fruits, more bodies touching while exchanging fluids and so on.
The case is made of stained recycled pallet wood (pine) which I joined using fingers joints and then it's been sanded and polished several times using danish oil. The panels are old circuit board that were skipped in an educational environment and that I recycled from being dumped. Rather than using them as PCB here they are used like panels."
