Hawkind's Putney?

via this Craigslist post:

"The original portable synthesizer introduced in 1969. A solid Aformosia cabinet housed the following modules interconnected by means of a matrix patchboard that uses resistor pins. Comparable to a Moog System 1P or 12, Arp 2600, EML 101, Roland 100.



Module complement:
3 x Voltage Controlled Oscillators.
Noise Generator.
2 x Input Amplifiers.
Ring Modulator.
Voltage Controlled Low Pass Filter.
Trapezoid Envelope Generator.
Voltage Controlled Reverberation.
Meter.
2 x Stereo Output Amplifiers.
Joystick.

This is a pre- Prestopatch unit. It is an earlier model that has had the power supply upgraded. It is autographed by Dave Brock of Hawkwind. VCO3 works,veneer, needs adjusting (if you want, I like this flaw). This is one of the most musical sounding VCS3 I have ever seen. Many sound like lab gear. The same is true with Minimoogs. That's why Alien Planetscapes and Hawkwind used this synth and kept it in the family.

It has a DIN pin input for an external keyboard or you can run a guitar, keyboard or mic through it. right now we are just moving the joystick around and getting great Doctor Who sounds. This style unit was also used by Brian Eno, Pink Floyd, and The Who ('Don't Get Fooled Again').

Those things next to the pin matrix is an oscilloscope output, which on later ones is derived from one of the other ports. This machine is very rare. It is a Mk 1 and the pins are original handmade probably by Zinovieff."

For the archives, this one is listed at $5300.

Update: This is the same one from this post. Looks like the price went down. Consensus then was that this was not actually owned by Hawkind, but rather only signed by Dave B. Via ps in the comments.
