[QuadList] What mechanical parts would one need to get a quad working?

[chill315 at aol.com]

I have to agree with Don.  These machines are being restored to a working condition.  Do what it takes to make it work.  AC Power cables are not going to make a difference if black blue or even pink.  

Now other areas of the machine that are electronic, then try to get the correct parts.  

I was thinking more about this and how much can one change out with not degrading the performance.  The TBC has to be able to handle the head switching.  There were only a few that did that.

The "pigtails" that supply Colortec, Amtec, etc. are fairly simple, but some of the distribution wiring is harnessed in with other wiring such as in the case of the AC supply for the audio frame.

As noted above, where the AC is bundled with other wires and cables, I prefer to have the power cables be more obvious so they don't look like a piece of RG-59.  In those instances, including the wiring to the frame-mounted power strips, I use yellow or orange "extension cord" cable of the correct gauge.  That makes it very easy to spot in the bundles.  For the pigtails, I generally use light gray IEC power cables cut to length, removing the female end and replacing it with the original connector. Obviously, black or any color would work, but again the light gray makes the cables easily distinguishable and I seem to accumulate lots of extra IEC cables, so it's a convenient source that eliminates having to make up one of the connectors.
