Speaker Jack Wiring Question - 4 ,8, & 16 Ohm secondaries

[Wittgenstein]

Either is OK.
Although the std mono-non shunting jack is the easiest way to do this, .... it doesn't really matter if you use the switching jack as long as you do not solder a grounded wire to the middle lug, (the switch bar). Even with it closed, it won't short out to ground with no ground applied.
Some times I'll run into a repair where the tech didn't realize how those work and they will have bent the switch bar away from the tip bar... all they needed to do was unsolder the grounded jumper wire.

Sorry I think I mispoke... the main 8 ohm output jack that has three lugs (as seen in layout) is a switchcraft 12A shorting jack and not a switching jack.

Moved discussion here (to my previous post) to consolidate all threads into one. I posted pics of my second attempt in that thread as well.
