"Monophonic analog synthesizer released in 1979...

The CS-20M features 2 VCOs with a 6-octave range and 3 waveforms. The VCA contains an extra sine-only oscillator, and a white noise generator is also included.

Like on the other early CS-series synths, a resonant 12dB/octave multimode VCF is available as the filter. It is switchable between high-, low- and band-pass (the last being 6dB/oct). The VCF contains its own ADSR envelope generator plus controls for cut-off and resonance.

The single LFO can be used for PWM. An internal memory is available, holding up to 8 user programmable patches. Other features include brilliance control, portamento, pitch bend, glide and glissando. For external control there is a CV/gate interface."

Vintage Oberheim STRETCH DX SN D32636

"Stretch adds MIDI and 4 or more extra sounds among other extra features. This one is loaded with "electric kick" which sounds 909'ish, Congas, Tambourine, Side-Stick and also a kind of gunshot/clap sound.

The main unit contains the original factory soundset, which is very similar to the DMX, in fact having owned the DMX and this I have to say I prefer the DX sounds.. they are crisper and more punchy to my ears.

All sounds are externally tuneable(unlike the DMX) and have their own separate output!"

Analog Craftsman 5U Dual Wasp State Variable Analog Filter

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

"This is a brand new dual Wasp state variable analog filter hand built in the USA by analog craftsman. The panel is based on the original design of the EDP Wasp keyboard synthesizer (the picture of the original wasp in this posting is just for reference and is NOT included in this auction). This module uses NOS Harris 3080 OTAs. The main output is switchable between LP, BP, and HP. There is also a separate output for the notch filter (as the original Wasp didn't have this). Also features CV input attenuator and a variable distortion circuit on each filter. The output of the A side is normalled to the input of the B side so you can use the two filters in series without additional patching for some VERY drastic timbres. If you know the Wasp filter, you know it can scream.

Again, this is factory new, fully tested and ready to ship. Also remember it is TWO discrete filters in one module, which is reflected in the price. There is no commercially available 5U build of this so here is your chance to own a custom build of one of the most unique and historic analog filters."

"Up for sale is a (1) very rare Solina (ARP) Explorer I front panel. It was part of a Solina C112S organ. The front panel circuit is the same as an ARP Explorer I and is in good condition, the sliders and switches are clean. The vco board is a 4027-1 version (same as in the ARP 2600) and the vcf board is a 4075-003 Rev. A version (same as in the ARP Odyssey MKII). Notice that the knobs on all sliders are missing. We sell this front panel with boards as-is, for spares or parts."
