Tube Rejuvination
Hi All,
I have been using a rejuvinator for way to many years. I guess the best way to describe how the rejuvinator restores the guns is by comparing it to the burner tubes on your weber grill.
As crud builds up on the burner tubes there is less transfer of heat to the cooking grate. So by cranking the Temp up on the grill and letting it sit for a bit you burn off the crud.
I was was taught to lightly tap the neck of the tube with a PLASTIC Alignment tool to knock the burnt off particals while using the cleaning position on the Rejuvinator. Dose anyone else do this?
Some other things to do while going threw the monitor.
Un plug the game.
Get a Mirror so you can see what you are doing to the game if you leave the monitor in the game.
1: Cap the monitor
Discharge the Monitor Even for a Rejuvination.
2: Check the pins on the neck of the tube. I have found were there have been slightly tarnished and cause a poor transfer of signal for one of the colors. I use a small strip of 000 sand paper. never touching the pins rolling just the strip of sand paper. Tubes still hold a slight charge.
3: Reflow the solder on the Hot spots on the board with silver solder. Silver solder has a higher melting point.
4: If you clean a tube you will have to balance.
5: The screen, and the neck board adjustments will probable need to be readjusted.
In the front of the Wells Gardner manuals theres a good explanation.
I have gotten to the point were I eye balance the drivers and black level pots.
Allways use Plastic alignment tools. Some have a very small piece of metal that is fine. I also picked up a 18 inch alignment tool so I could reach down into the chasie and adjust the Horizontal width pot. with out having to get my large hands involved with all the points of "pain" on the monitor board.
Priore to turning the monitor on. I verifiy that I can easily turn the Pots on the neck board.
Depending on the level of dirt on the monitor I pre spray the pots with Electronic cleaner and let them dry a bit. I move the pots slightly left to right. This helps clean the pots since they have been sitting in one position for sometime with dirt on eaith side of the swip.
Somethings to remeber.
If the One color is stronger than the other colors. Green, Red or Blue. Then the other 2 colors could be weak. Levels turned down.
Example:
Red is over driving the screen after you have capped and Juved. This could mean that the Blue and Green are set to low allowing the Red to dominate. Red was at the proper level the whole time.
Use the single color test screen in your games test mode to balance out the colors intensity.
Also check the White screen to see what color is either over powering the screen or the others are still set to low.
Look at the black area in the color bar Pattern screen to detrmine what color(s) are either set to high or low for your Black level color adjustment pots on the neck board.
A rejuvinator wil not effect the heater coil or the Focus. A cap kit will to a point because you are most likely to raise voltages to what they should be and raise the High voltage(Horizontal circuit). Might be a K or 2 but it dose make a difference, thus inturn improve the performance of the Tube. Cleaning the pins and resoldering the neck board solder points will help.
Green is the dominate color Followed By Red then Blue. The Blue color makes up the smallest percentage of the overalll picture. Blue will allways look soft compared to Green and Red.
Same holds true when having to do a convergance on the tube using the magnetic rings on the neck. The Green hatch pattern is the point of reference for the other 2 colors to lay on top of and make the white lines.
After Capping and Rejuvinating the Tube. Run a Degausser Coil over the tube when the game is First turned on, Prior to doing any adjustments. This will save you going off in the wrong direction when you start to do your adjustments.
After I am done I Deguase again.
And yes, rejuvinating a tube will shorten its life. But at this point who cares. It needed to be done and the monitor needed to be replaced anyway. So you saved your self some bucks and got another X amount of years out of the game.
