Morley Serge - Final restoration pics & notes

The Morley Serge restoration is 99.99% finished.
I can't wait to have a play with it.

Here are some recent pics of the Serge kindly supplied by Ken Stone.

Here a test run video:

According to Ken there are a few quirks. Osc 1 and 3 track each other relatively well.
The others not so well. They are all very very very early (1st Generation) Serge oscillators ... not 1V/Oct
and we are actually lucky to have any tracking at all. :-)

Whether the VCOs track or not is not a problem.  It's all part of 
having a vintage paperface. They are fun VCOs all the same.
One Neg Slew is WAY slower than the rest.It was decided to leave
it at that speed because it is of more use for clocks and so on. 
More info regarding the Negative Slew can be seen here. :-)
The chaos bank has two inbuilt mixers. One mixes the 8th outputs of each of
the three generators. The other mixes steps 5,6,7 of the bottom generator only.
When nothing is plugged into them, the Black inputs of chaos bank pull high,
while the red ones pull low. That means if you don't plug something into the
black jack, the exclusive or gate is set to invert. 
Patching any of the outputs into the red jack then creates a divider, so you 
at least get a square wave out of the generator.
