TTSH - Two Thousand Six Hundred

Music synthesizers… I think I was about 10 years old when I first heard Jean Michel Jarre's Oxygène on the radio. Ever since I have developed a strong interest in electronic music. Well, maybe not all kind of electronic music. Also having interest in electronics and later doing an electronics (plus computer science) study, in my youth I have been working on my own analog synthesizer. The first trial in the early 1980's was kind of primitive (no comments…):

My first trials in building a synthesizerBased on a book “Elektronische piano's en synthesizers” by Helmut Tüncker from 1976.

Later, mid 1980's, I started over with something based on the Formant DIY modular synthesizer from Elektor magazine, but never finished. Here you can see already the power supply, which I'm planning to reuse for my current project:

Unfortunately I haven't made that much more photos at that time, so not much to see.

Time elapsed…

Early 2014 I came across information about an scaled ARP 2600 remake as DIY kit from The Human Comparator in Sweden, called TTSH – Two Thousand Six Hundred. Hey, that looked nice, why not give it a try! Unfortunately it was (and still seems to be) quite difficult to get the printed circuit board and front panel that the kit exists of. [Update 1/2016: As of early 2016 the TTSH kit is sold out and seems not to be produced anymore.]

Early February 2015 I was lucky and was able to order the TTSH kit. Meanwhile this is version 2, with several improvements and fixes over the initial version from 2013/2014.

The ARP 2600 was a famous semi-modular synthesizer in the 1970's. The Vintage Synth Explorer site shows some details on it. Just search the internet to find more information and e.g. demo videos. Likewise you should be able to find more on the TTSH. Some forums deal with it, like the ones at Muff Wiggler and Sequencer (in German). Also DSL-man (in Germany) does a good job on the TTSH.

Here is mine:
