ETI 4600

[Edward Leckie]

I contemplated building this beast a couple of years ago. I've even got the
original ETI magazines that spans about 3 years from 1973-1975. The unfortunate
thing is that it requires +/- 7V, +/-14V  and 5V power rails and all the PCBs
were quite large.
There's a place called RTS in Hurstville that will make the PCBs that are in the
articles. The VCF uses a switch cap method for voltage control, in case you're
wondering. The author also states that his filter design is patented! Doesn't a
patent only last for ~20 years?

The best thing was the groovy wooden case.

Ed.

Has anyone built this machine? Would it be a good first "major project"
to undertake?
It appears to have a lot of non-standard features, like all CV and Audio
inout/outputs are between 0V and 5V, not -5V and +5V on some other
machines.

Any sugestions?
