Re: Anyone know what setting these Japanese tools were used in?
I do not think so. I
think was smaller...my memory is fuzzy ...been too long....There
is a size in between the 3.5mm ( 1/8 inch) and the 1/4 inch IIRC
3/16 and there is/was one larger than 1/4 inch 5/16 or 8mm.

Is Bell System "phone jack" not the same as 1/4"?? The drive
marked headphone jack does not fit Bell System "phone jack".

Doesn’t fit in what sense? Is the center shaft too big to fit a 1/4” jack?
The rest look very handy for working on the earphone jacks of transistor radios.

the Head phone jack
items are for the thin, threaded trim rings( nuts)? that were
used as nuts on 1/16, 1/8 and 1/4 inch headphone phone jacks.
these were prevalent before they started using thin nuts on
front panels.
the rest seem to be for similar items used for front panel
mounting or special trim screws. ( I have a few I made years ago

Search on groups.io for "test equipment for sale or trade". The group is named something like that.

Re: 2465A Service Manual - rev. October 1988
Not sure.? If you do not see exactly what you need, e mail them. They are good about replies, or at least used to be helpful.????
Their schematics are especially good high definition scans, well worth the money IMHO.

Re: 2465A Service Manual - rev. October 1988
I'll check them out, are you sure they have the correct revision?

Also the 1A1 physically won't fit. You need the 3A6. See the Tek Wiki for details.
