This information is intended to be a resource for doing DIY, repaneling, and/or repairs on 5UMU systems. It's Atnot presentcomprehensive, someeveryone ofhas thispreferences, informationbut is very difficult to find or otherwise available. Withlists the growth ofcommon/major/most-wanted interestparts in DIY for boththe MU and MOTM formats, it seems like an appropriate time to start thisformat, and/or compilewhat assort much information as possible inof athings singlewill placework.
If you have any corrections or additions to this list, feel free to make them here, or send a PM to '''diophantine''' on the MuffWiggler forum. I plan to eventually add some HOWTOs, FAQs, pictures, tutorials, and schematics. When I do that, I will likely split this out into multiple pages. For the present, while it is very much a work-in-progress, let's keep this as one page for ease of use & editing.

Panel components sold by Synthesizers.com come with 6" wires and MTA connector.
===PCB Mounting===
Synthesizers.com and some independent manufacturers mount the PCB parallel to the panel with [[standoff]]s, others mount PCBs perpendicular MOTM-style. [[PCB mounting bracket|4-40 steel mounting bracket]]s are fine for this and also work with [[CGS]] boards.
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 steel 3/8" black oxide phillips pan head screws,<ref name="gf">Guitar Fool:[http://guitarfool.com/modules/hardware.html Hardware]</ref> are available from [http://www.aaronsmachinescrews.com/cfusion/DisplayProduct.cfm?ITEM=1701SN1368 Aaron's Machine Screws].

==Internal connectors==
* Synthesizers.com: http://www.synthesizers.com/cabinets.html#parts
Dotcom uses MTA-100 connectors, using 24 awg wire. To fit the wires to the connectors, use the AMP MTA key style maintenance tool: AMP 59803-1 (DigiKey: A9982-ND).
====MUModule Jacks=power===
Power supplies are connected using 6-pin keyed MTA-100 connectors.<ref>[http://www.synthesizers.com/technical.html#internaldc Internal DC Module Power - 6 pin MTA]</ref>
Dotcom modules use enclosed Switchcraft-style jacks.

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.
===Panel connectors===
2-pin MTA-100 connectors are used to connect jacks, push-buttons, and LEDs.
PCBs can be mounted parallel using 1" (Mouser: 534-8405) and 1.25" (Mouser: 534-8407) threaded standoff posts.

==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.
