Panels Parts

MOTM

Knobs

MOTM uses ALCO PKES90B1/4 knobs.

Available at:

Pots

MOTM uses Spectrol 149 pots.

Available at:

Switches

...

Pushbuttons

...

Jacks

MOTM uses Switchcraft 112A 1/4" jacks.

LEDs

MU

Knobs

Dotcom uses fluted dual-dot 1" Moog-style knobs.

Available at:

For pointer knobs, Dotcom uses 1.125" Moog-style pointer knobs.

Available at:

Pots

Synthesizers.com uses Alpha single-gang 24mm pots.

Available at:

Switches

Available at:

Pushbuttons

Available at:

Jacks

Dotcom modules use enclosed Switchcraft-style jacks.

Available at:

Of course, other open-frame 1/4 jacks can be used (and are used by 3rd party manufacturers), and are especially handy for normalizing jack connections.

LEDs

...

Note: Panel components sold by Synthesizers.com come with 6" wires and MTA connected.

PCB/Panel Mounting

MOTM

PCB Mounting Brackets

MOTM PCBs are generally mounted perpendicular to the panel with L-shaped brackets affixed to pots or jacks.

Available at:

Details on Stooge brackets: http://www.wiseguysynth.com/larry/brackets/modular_brackets.htm

MU

Synthesizers.com and some 3rd party manufacturers mount the PCB parallel to the panel with standoffs. Other 3rd party manufacturers mount PCBs perpendicular MOTM-style. #4-40 mounting hardware is ideal, and works with CGS boards too.

PCBs can be mounted parallel using 1" (Mouser: 534-8405) and 1.25" (Mouser: 534-8407) threaded standoff posts.

Black oxide screws, like the ones used by Synthesizers.com, are used to affix the standoffs to the front panel. Specifically, #4-40 x 3/8" Black oxide phillips pan head screws. [1]

Screws available here: http://www.aaronsmachinescrews.com/cfusion/DisplayProduct.cfm?ITEM=1701SN1368

For perpendicular mounting, brackets as mentioned in the MOTM section can be used, or threaded right-angle brackets (Mouser: 534-621) can be mounted to the panel, using the same screws mentioned above. [2]

Internal Connectors

MOTM

Module Power

4-pin MTA-156 connectors

Pinout:

  • 1 = +15V
  • 2 = GND
  • 3 = GND

  • 2 = KEY - pin missing and plugged
  • 3 = +5v (Red)
  • 4 = gnd (Black)
  • 5 = -15v (Green)

Female 24AWG cable mount: AMP #6404416 (Mouser: 571-3-640441-6)

Male PCB mount: AMP #6404566 (Mouser: 571-6404566)

Panel Connectors

2-pin MTA-100 connectors are used for jacks, push-buttons, and LEDs.

Jack Pinout:

  • 1 = Signal (tip)
  • 2 = Ground (ring)

Female cable mount: AMP #6404412 (Mouser: 571-3-640441-2)

Notes

  • I'm not wanting to do a list of every possible panel part or knob (everyone has preferences), but to list the common/major/most-wanted parts in these formats, and/or what sort of things will work. I'd love to eventually list the sizes and have templates/sizes for panel design too.
