/* ---------- "MOV's and tubes" ---------- */
Two things:
1) I think this has been discussed on the net before, but I didn't
follow it at the time--is there any way to test whether a MOV
is still in working condition? I have a power strip that
has three MOV's the number on them is:
MDC
Z131
20ULB
I don't have a data sheet on them. Is there any particular importance
to their placement on a strip? This strip is laid out like this --
(looking from underneath)
(hot) /- - /- /- - -
/ MOV /
(ground) .47uf400V - / - \ - MOV - - -
\ MOV \
(neutral) \- \- - \- - -
Anyway, I think the strip might have had lightning go through it. Besides
just replacing them, is there any way to TEST whether they are still good.
While we are at it, in what cases are MOV's effective--small power surges,
voltage variations caused by large motors, lightning strikes, induced voltage
from lightning, static charges.
2) Does anybody know a good source for tubes for VT125 terminals. Good means
cheap, and a reasonable (4 - 8 weeks) delivery time. In general, what are
good sources for CRT's? Has anyone tried to use "rebuilt" tubes? How good
are they and how long do they last?
