This information is for doing DIY, repaneling, and/or repairs on MOTM systems. It's not comprehensive, everyone has preferences, but lists the common/major/most-wanted parts in the MOTM format, and/or what sort of things will work.
Panels/Faceplates
Specifications
MOTM panels use U, the 19-inch rack unit for height and width. The height is 5U (8.75"), while the widths are in multiples of 1U (1.75"), with some fraction less to allow for manufacturing tolerances.
Blank panels
Blank panels can be purchased from:
- Bridechamber 1, 2, 3, and 4U
- Synthesis Technology 1 and 2U
Project panels
Panels for specific projects (CGS, I. Fritz, etc.) can be purchased from:
Custom panels
Custom panels can be manufactured by:
- Re:Synthesis, UK
- Front Panel Express, USA
- Schaeffer, EU
Panels parts
Avoid cheap parts, especially if mechanical. Invest in quality, you always get what you pay for. Otherwise your entire system might later develop intermittent faults.[1]
Knobs
MOTM uses ALCO PKES90B1/4 knobs, available at:
Potentiometers
MOTM uses Spectrol 149 pots, available at:
Switches
NKK toggle switches with bat handles are the closest fit.[2]
- SPDT: NKK M2102ES1W01 (Allied: 870-8646)
- SPDT center off: NKK M2103ES1W01 (Allied: 870-8647)
- DPDT: NKK M2022ES1W01 (Allied: 870-8652)
- DPDT center off: NKK M2023ES1W01 (Allied: 870-8653)
Jacks
MOTM uses Switchcraft 112A 1/4" jacks.
LEDs
MOTM uses 5mm flat-lens LEDs.
- Red: Lumex SSI-LXH387ID (DigiKey: 67-1155-ND)
- Green: Lumex SSI-LXH387GD (DigiKey: 67-1156-ND)
- Yellow: Lumex SSI-LXH387YD (DigiKey: 67-1157-ND)
PCB/Panel mounting
PCB mounting
MOTM PCBs are generally mounted perpendicular to the panel with stooge brackets affixed by the pots or jacks, available at:
Internal connectors
Do not mix dissimilar metal terminals and headers. The contact resistance will go up with dissimilar metals, causing all sorts of problems.[3]
Power
MOTM modules and power distribution boards are connected using 4-pin MTA-156 connectors and 18 awg wire.[4] Systems by Encore Electronics use 4 pin 0.156" Molex KK connectors, while those from Oakley Sound Systems use either MTA or Molex KK 0.156" connectors.
Pin | Voltage |
---|---|
1 | +15 |
2 | GND |
3 | GND |
4 | -15 |
- Female cable mount: 640426-4 (Mouser: 571-640-4264)
- Male PCB mount: 640445-4 (Mouser: 571-6404454)
Interconnections
Oakley Sound Systems designs use either MTA-100 or Molex KK 0.1" for board interconnects.[5] Template:From Muff Wiggler wiki
