Cap Kit Install Videos - Informational
Boingo:
I loved the videos except for one problem. In the second video, the guy kept referring to the capacitance values as "uF" instead of "µF". I know "µ" looks lot like "u", but it is actually the Greek letter M. In the SI (metric) system of prefixes, "µ" stands for "micro". The Latin M or m could not be used for "micro", because they were already being used for other prefixes ("Mega" and "milli"), so the Greek letter M (µ) was used instead. At first I thought he had said "µ", pronounced "moo" like what a cow says, and that I had just heard him wrong, but as the video continued, it was clear he was saying "u", not "µ"
BTW: µF stands for microfarads.
Sorry. Just something that was bugging me.

Nice vids !
Like it's mentioned in the third video (but not in the 2nd !) do not assume that the silkscreen printing is correct. Check the polarity by how the old cap is installed. IIRC the G07 is one of the monitors that have an error in the silkscreen.
Another tip: the solderings on those monitors are very old and won't flow easily. Add a little new solder tin to make the old solderings flow much easier. This also prevents you from overheating (because the old solder won't flow).
Also, on the second video the guy is moving the iron to "smear out" the solder. That's a big no-no. Basically you put the iron at the right spot and hold it there, let the solder flow into it's natural "position/setting" and then simply remove it. Don't allow the part or leg to move during the setting of the solder, or you'll have a cold solder joint.
Just some details, otherwise these are great tutorials :)
georgemcfly:
If the monitor in my cab has terrible burn in, and i want to replace, do i need to discharge it first? Or is it safe to pull, and destroy redneck style?
SirPeale:
You can pull without discharging, but I urge you to find some that wants it for either parts or repair.
moose:
As far as caps specifically go, do they need to be discharged (not the tube) before removal? I know they hold charges, I don't know how long for though, or what a safe way of making sure they're drained are.
Also, for discharging the tubes, should the power cord be plugged in to have a ground connection to the outlet or not?
