I think the C87 was about the last of the CMs built by NEC. They were
pretty decent sets, but no Sams coverage could make them tough to fix.
It's been a few years, but I think this was one of the models the
electolytic capacitor off the driver transformer would open and cause
the horiz output to short. Flybacks were also sometimes bad. Ought to
be able to fix for under $200 for sure I'd think.
