"Testing my old homemade 1975 synthesizer after cleaning, repairs and restoration. It's been sitting gathering dust and grime for about forty years but still works, just need to iron out a few more bugs still."

Some info via the seller: "Ok...., as far as i can tell its a finished project all parts there on the circuit boards with just a few wires to connect, keyboard and power supply socket which i have.
I had an external power supply made up by a professional who knows his synths, (ex BBC tech)
he has been inside these beasts before.
He thinks the power supply may have been taken out and an external one used as inside is a reverb tank that could have been picking up interference from the original, Makes sense.

The keyboard itself looks as if its never been played as its in excellent condition and is still in need of fixing down, about 4 screws i think but all the wood inside it fixes to is fitted.

This will definitely need servicing and some of the pots/controls are a bit stiff so some spray could well sort them out, also as you can probably tell if you know these synths is that its missing all its coloured caps, i personally think it looks far better like this and not like a toy but again these can be easily sourced if you wanted it totally original.
It has 6 of the original pins for the matrix board and i will supply info as to where to get more if you want them, i have collected all i could from the web about this synth which includes the original building and setting instructions plus other stuff."

"ETI 4600 synthesiser demonstration. This is being sold on eBay from August 15th 2012 and ending on August 25th. World-wide shipping is available. This is an overview showing the complete 1970s vintage analogue synthesiser with an overview of the modules and layout.

This synth was a state-of-the-art design when it was conceived back in the1970s. Designed by Trevor Marshall in 1973, this synthesiser was offered in kit form by Maplin Electronic Supplies (in the UK). The parts cost was around £500, and was said to match the performance of synthesisers costing £1500 - that equates to a staggering £15,600 in today's money (according to www.thisismoney.co.uk calculator). This is a collector's dream! This actual synthesiser is featured on the home page of www.eti4600synthesiser.org.uk website, is fully working, and is in great condition considering it is some 35 years old. This synthesiser was built by me in 1977 when I was a teenager and has remained in my possession until now.

Not only is this a great asset for lovers of nostalgia and early electronic music history, but also for the modern day sound design engineer who can sample these great 70's sounds and combine the wonderful early synthesiser sounds with the precision, reliability, automation, and flexibility of modern DAW's!

See the other 3 parts for an in-depth demonstration."

"All components, pcb, keyboard, casing and internal hardware were supplied by Maplin in semi-kit form.

I personally constructed this in the late 70's , Maplin workshops set up all the boards that required it.

There is still a very small amount of work to do on this synth to complete it, the springline requires wiring in which is approx 4 wires, the joystick also requires final wiring up which is another small job. Anyone who remembers these synths will know about electronics and be able to follow the manual to complete it. The synth did play back in the 70's but I haven't used it since, I also don't have speakers etc now to listen to it on so I'm unable to run it now but there is no reason why it shouldn't work. You may find that some of the tantalum capacitors will require changing, it's usually the case with tants of this age, at least they would pop on my old Nascom which is from the late 70's. There is a very detailed manual which will come with the synth showing all the circuits and construction details, there is also a considerable number of pins for the patchboard. I have removed the back of the instrument whilst taking the photo's of the circuits for clarity, there is normally a back fitted."
