The NTE538 or ECG538
voltage tripler will work quite nicely in 465, 465B 475, 457A
scopes.? Connect the D and LOW taps to ground and do not use the
FOCUS tap.? Cut the end off the original tripler and splice it onto
the new HV lead.? Use a thick plastic piece of tubing around the
splice and fill with silicon to insulate it, make sure there are no
sharp wire whiskers on the splice or you will get a corona arc.?
Drill two holes in the metal chassis where the old tripler was and
mount the 538 with two screws.? You might have to trim a little
metal from the aluminum cover that covered the original tripler.

Since it appears that high voltage multipliers for the
older scopes such as the 465 are virtually impossible to
find, does anyone have any experience or thoughts on
building one? I've heard of them being built and I'm
willing to give that a try but I don't know if the
multiplier in the 465 is 3X, 4X or whatever.
Thoughts?
Dan,
