but the one I got from a local shop was a t3.15al 250v which i didnt

does anyone know exactly how to read the color code on radial through
hole inductors? They have two small color dots on top and one or two

that the G2 is a regulated voltage, unlike most units.

What would be causing a Moire effect on a new CRT SDTV? There are
smally wavy lines that appear on the middle sides of the tv. I'm
pretty sure they're moire effects. They only appear in a spot that's
maybe 2-3 inches in diameter.

I was browsing through a Goodwill thrift store in Interstate 20 a bit east

was a portable TV set.  It looked like recent manufacture, but on top of the
set, right in plain sight where no one could help seeing ...

I've got one Philips DVD (DVD634) for fixing. The problem is a dead power
supply. In that power supply, the actual broken (exploded) part is smth in

being out of ink, color & Black.  I went to the local walmart to
pick up a couple new ink carts.  HOLY CRAP>>>  Over $50.00
plus tax for both carts??   I notice next to the ink carts sits a ink

Looking for one of these, can't find them on the net. Anyone have one

I'm trying to track down a rather odd problem with an 1993-vintage HP
Laserjet 4.  On occasions the printer works fine, test prints and parallel
