Metro Modular 2196 - Dual Phase Shifter - Build notes

These are unofficial build pics and notes for the Metro Modular phase shifter.
Please check this with the official notes when they come out.

There are two inputs.
Each takes one audio signal (above 1.7Hz) and outputs two signals that are out of phase with one another.
You could use it in conjunction with a ring modulator to get some frequency shifting.
A quadrature signal would also be useful for driving the Boethian Wheel - Model 660

The module is in 4U Buchla format.

I'll be updating this as I proceed with the build.
The MM2196 goes by the name "Roselands" which is a Sydney suburb with the same postcode.

There are 2 identical PCBs for each module. So you need to double the BOM
The BOM for each board is:
(Please check this with the official notes when they come out.)

Resistors:
10R x 1
100R x2
220R x 2
680R x 2
1.5k x 2
3.57K x 18
10k x 2

68K x 1
82K x 1
100K x4
150K x 2
25K trimmers x 4

Capacitors

470pf - ceramic x 2
4n7 - polyester x 2
47n - polyester x 2
470n - polyester x 2
100uF - electro 16V x4
1uF - electro 16v x 1

Transistors
+ 11 x Mouser No: 512-BC560CTA
BJT TO-92 PNP 
+ 11 x Mouser No: 512-BC550CBU

BJT NPN

Misc
Tiny Jacks x 11

Ps where it says 3k57 for the resistors, 3k6 are fine.
Stick with 1% for resistors on most things in this build. 

470pf and 220pf are ok as C0G (single layer ceramic) or NP0 (ultrastable or temperature compensating capacitor) ceramics, make the others polyester.
The electros can be 16V

These are the trimpots I'm using.

Standard Buchla connector to the front-Only need the +15 and Q lines.

 The transistors that I'm using are:
 bc560

bc550

Way to assemble is to put one board (with power connector) on, screw it in place between the spacers, wire it up and calibrate. The three pins (SV1) behind the power connector can be used for a 3-pin header pin/socket pair that you then solder onto the next board stacked above. Screw it in, wire it up and calibrate. You’re done.

Calibration frequencies. (Left to right) use 10hz, 100hz, 1khz and 10khz sine waves.
