9.
Mount the component pcb onto the front panel again and screw on the pots from the front side.
10. Make sure everything is in place.
11. Solder the banana jacks in. You can either solder them directly to the surrounding vias (i.e. the
ring around) or - which makes removing easier should you ever need to do that - by inserting a stiff
(bare) wire into the little hole (via) and solder that wire to the top of the banana jack:
12. Attach any screws / spacers if desired and mount the main pcb onto the component pcb.
13. Connect a power cord sup12V, GND, GND, -12V to the MTA-header on the main board and
you should be ready to go :-)
Calibration
Using TS, the
voltage for the CMOS parts
can be adjusted to precisely. The theoretical value should be
5.155V, however, I found that 5.115V worked best in my case. Use a good digital multimeter and measure the
voltage between the 2 test pads (next to the 4520 IC, marked “ - TEST -” and adjust the trimmer. You can also
run the stepped output into the 1V/Oct input of a VCO and adjust the trimmer so that the pitch of the oscillator
stepping up stays in tune.
