Junction box? Do you mean the step up transformer?

Does the error have to do with the height of the spindle on the outboard motor? Did it not initially line up with the plane of the platter?

Nope. I knew it wouldn't line up 'cause I made the plinth over an inch thicker than spec.

Good guess!

It doesn't look like the step-up, but I could be wrong. I'm talking about the interface between the tonearm leadout cables and the interconnnects going to the tranny or phonoamp. I believe this is usually referred to as a junction box, but I don't know why it's needed. Is it typically nothing except wired-together jacks inside a box?

That's the step up. It's a K&K Audio passive tranny. Works great. It allows the use of a low output MC cartridge like my Denon 103r with the built in phono stage (MM) of my Audio Note Soro SE Phono.

Why would you want an interrupion of signal that has no purpose? If you just needed to extend them, you could use a good set of male to female rca's. Tonearm to tranny to preamp, shortest path possible with my cartridge/tranny/preamp setup.

Hope this clears it up!
