Yes, 0 on pin 6 with respect to pin 6. See the cross symbol next to the '0V' on the chart ?

What that means is but the negative lead of your meter on pin 6, not the common negative while taking that reading. So naturally when you also put the positive lead of your meter on pin 6, you will get 0 volts.

I think looking at the contrast control is the easiest way to tell.

The early TS-4J is just a standard three terminal pot.
The TS-4J late has two extra taps and several capacitors mounted on the pot.
