Hello all
The resistors spoken about above were VERY COMMON with older TV's with a seperate LOPtX and Tripler combination.
....LOPTX = Line Output Transformer.
....Tripler = Triples Line Output Transformer Voltage.
Follow closely here....
A TV Cathode Ray tube needs around 30 KV to operate with a 68 CM tube. Years back, the Standard here anyway was a separate LOPTX and Tripler combination. So you need both the LOPTX and Tripler to see a picture....
Back to the high value Resistors. These were used to used to Focus the TV from the Tripler.... a special third pin on the Tripler.
These high value and high voltage resistors started @ 5.1M for a Philips K9 chassis all the way to a 47M on a Telefunken 711 Chassis.
Depending on what you needed to do to bring the Focus in.
Nowdays, it is way too easy. All is built into Minute packages that you adjust with a simple twist of a POT for Focus or G2. No Triplers anymore and it's become a free for all.
That is why every Tom, Dick and Harry think they are capable of repairing a TV.....until it belts them.
Seen it all. That 30 KV stays the same. No matter what.
Fun and games. I was taught the safe way. I rarely shock
. And if I do, I have been lax. Wake up call and all.
I respect HV big time. It is really sore to get belted.
