Re: Another reason to build an X/Y monitor

We actually considered doing the ZVG as a kit, but opted not to. Here are
the problems.
The components (ICs, resistors, etc) come packaged in tubes or reels, and
in order to provide a kit, it would actually take us more time to repackage
individual ICs and count passive parts (i.e. 10 of these, 5 of those).
Another issue is one of support, as compared to having it professionally
assembled. With everyone assembling their own board, someone will
inevitably put a chip in the wrong place, static zap an IC, or maybe we
mess up and short you a part. Any of those errors would result in a phone
call to us, and further time spent to resolve any problems.
When you look at the savings by not having it assembled, it quickly gets
offset by other overhead.
As far as the schematic goes, it will be included in the owners manual.
This material will also be available online. I always liked when stuff I
buy comes with schematics, so we figured we would publish it even though no
one else does anymore. :(
