Vacuum tube wiring

I have a couple of old vacuum tubes that I would like to light up for my grandchildren on my train layout. I also have a Chicago Transit Authority control panel with the throttle for one of there older trains that I would also like to light up.

Where can I find wiring diagrams so I can wire them up to light? I don't want any outputs from the tubes or from the control panel so they kids won't get hurt!

Thank you,

Ed Goldin

What you need to do is find the model number which should be on the vacuum tube somewhere, then web search for "<model number> datasheet" without quotes, and look for the filament pins and the filament voltage, wiring that as it says and you'll be good.

How can I dismantel an old tv picture tube. No recycling near by. Do not want it to blow upl

They don't explode the IMPLODE. They are under a vacuum.. To render them safe the manufacturers recommend that you take an ice pick and a hammer and put the tip of the ice pick at the back of the tube next to one of the pins for the tube, that plug into the socket and you gently tap the ice pick in till it breaks the seal on the tube and you hear air rushing in.

Just let your set unplugged for a couple of days since some models retain electricity in the aquadag.Then hammer away,the disposale of the tube and circuit is up to you and your local regulation.

I have a very old tv.small one in fact.when u press the power button it makes this cliking sound plus u can somewhat feel it 'activating' when u press when i press it i dont feel that 'activation'...

This may not be an adequate answer, but if it's old as you say, a few thoughts: It might be a Vacuum Tube type. The some of the tubes may have failed. A tube tester would reveal. Some of the capacitors may have failed. They depreciate with heat and age, A schematic (hard to find, but not impossible) and circuit knowledge would be necessary. Similarly resistors may have overheated and burned or shorted with the other failures (called co-lateral or consequential damages) The clicking you refer to, likely was the building up of static charge around the viewing tube. If any of the above failures occurred, it's likely that static voltage charge could not happen, therefore not the sounds you are familiar with. A TV repairman, can be found, not in the phone book or internet, because we've moved the universe into a "dispose-of old , and cheaper to buy new" environment. If the TV is valuable to you, sentimental value, what-ever, People may still do repairs, but you're going to have to ask around a lot.. maybe ask seniors at a church or two or three if they know of anyone who still does or knows how or know someone who does know. Well, there you have it. Best regards --- GooseBay_Camper
P.S. some churches have old Vacuum-tubed Hammond Electronic organs, the technician they use to service this equipment, may have usefull skills, or Musicians that use vacuum-tubed electronic amplifiers, or music stores that sell amplifiers may know of a technician they use that may have similar skills for Vacuum-tubes and old equipment. Again Good Luck. GB_C

Electrical Arching in back of tv

Check the connection of the ground. Bad connection of ground usually create this problem.
Especially the ground connection between the crt board and the wire who surround the picture tube. Let me know what you will get after this.

Tube TV - one thin horizontal line of bright light

Vertical defection failure. Common failure. Pretty easy to repair ($50-75?). However, my general rule of thumb is not to waste any more money on TVs over 10 years old. Too much other stuff in there ready to fail as well.

Sony Trinitron experiences

The screen control inside the set may be on the highvoltage transformer or on the crt socket; either way if you can turn it up just a little clockwise and the picture comes up but doesn't look good you are likely to have a bad tube. Or try tapping lightly on the glass neck and watch the picture as you tap. If it reacts to the tap you have a bad tube. but the turning the screen control is the best test. Turn it the other way the picture goes off immediately. bad tube: too costly if it is available.

Popping noise

The anode cap on the back of the tv tube is leaking the high voltage be careful as going into the back of a tv it store very high voltage and could be fatal.the solution to problem get a tube of clear or red silicone discharge the high from the tube,you do this by getting a alligator clip with wire attach clip to a ground wire on the back of the tube attached the other end of the wire to screw driver gently push it under the Anode cap you will hear a popping sound with i little sparks. remove the cap from off the tube get some alcohol wipe the dirt away apply the silicone around the anode and the anode cap place in on back and leave it to dry and cure for about 7 hrs close up back and turn on your tv and all the popping sound is gone.good luck.but if it is the wire for the anode cap that comes from the flyback is the one leaking change the flyback.again good me on or email me at

TV will not turn on when power button is pushed.

check the main fuse in the tv. test it with a multimeter, not visually. if its the thermistor that blew the fuse, it is very difficult to see the break in the wire. replace if blown. if unit blown fuse again withing a couple of weeks replace the thermistor in the degausing circuit. good luck.
