During my time in the U.S. Navy at USNAVSECGRUACT Sabana Seca, Puerto
Rico in the test equipment cal shop, I got to use the Lavoie "faux-
clone" of the Tek 545 every day for two years. I finally got tired
of its (and every one of them that I'd seen) problem: bright trace
that gradually dims over an hour or two to no trace at all. I
finally figured out that it must be the HV transformer so decided to
pull a fast one on the Navy and order a Tek replacement rather than
the Lavoie part number. Lo and behold, when the mil-packed Tek
transformer came it, enclosed was a sheet telling how to install the
Tek part in a Lavoie scope! Obviously, this was the premier problem
with this "design". We had two of those danged mainframes at the
operational site and they both had the same problem. I fixed the
second one within a month. Then I saw another one at another duty
station and told the techs how to take care of the problem.

I remember that the Lavoie scope had a little box filled with a
gillion neon lamps, all in series used as a voltage regulator as I
recall. And the ceramic strips were little metal clips in ceramic
notches rather than the fired silver-on-ceramic that real Tek's had.

Once I fixed the scope up, I didn't really have any complaints about
its operation but it always bugged me that it was obvious copyright
and patent infringement. Later, after I went to work for Tek, we'd
gotten the message that the lawsuit against the government, Lavoie,
Hickock, et. al. had been "won" by Tek.
