Frogman - Huh!? Red/Green, White/Blue; no?
It must be tough for cartridge designers being at the start of vinyl playback. I mean, once you get past the four exit pins, they have no idea what tonearm, loom/wires, TT, phono stage, rest of the chain / room.....is being used by their buyer. Does this weigh more on the minds of those making higher priced cartridges ?
You would think.....I would think.....that at least get the four pins exit points the same. Make it a standard. No ?
Case in point....See this picture

which clearly shows the cartridge lead colors.

Total opposites on PIN exit design. Why....Confusing ...Yes.

Harry - as discussed here before, I bypassed Bruce’ standard loom long ago. Even Bruce uses a straight shot in, but based on what you posted I went to dig out the old looms that came with the armtubes, to have a look. I found a couple. On the one, see here.

There are four red,green,white, blue wires with black coverings where the leads are connected. Now on the other one - definitely older - there are again the four wires - this time the coverings where they attach to the leads are color coded, and red one is black in color.
