Solved redundant question

[eliotcole]

This question may be irrelevant, as the previous question revealed that CRT Tubes are NOT voltage specific, so this doesn't matter.

What follows is the question as asked when it was believed that they are voltage specific.

Spoiler: Old Question Details

Yes/No - Can The Voltage That A CRT Tube Operates At Be Changed Without The Use Of A Transformer? ( eg 110v to 240v )​

---

Following this previous question, where it was revealed that CRT Tubes are voltage specific, meaning that any CRT tube cannot just be used on any voltage ... I am wondering if there is a way to change the voltage that a CRT Tube operates on without using a transformer to scale up or down the voltage.

I am not necessarily asking how it is done, here ... so no need to get into the weeds unless you are REALLY bored ... just need to know if it can be done without using a transformer.

It would appear that a CRT Tube doesn't care about voltage.

It is unclear to me what voltage do you refer to in your question.
If you refer to the main input voltage of an monitor (tube + chassis), then some times there is a jumer or switch that allows the monitor to be used with different voltages.

Like I say in the second comment, this might be a question that doesn't require an answer, @Georgian2 ... because it would appear that I asked it based upon an incorrect previous answer to the previous question.
It turns out that the CRT Tube is not really concerned about voltage.

Thanks, though!

I don't mean to hijack your thread.
This here makes so sense at all. Just for my understanding, what do you mean by CRT Tube?

 

[eliotcole]

The CRT Tube ... the tube that has the glass at the front, and a bit that the neck card connects to at the back.

Is that not the CRT Tube?

Sorry if I've got that wrong ... what's it called?

Yes, that's a CRT tube. Can be found in all sort of things from oscilloscopes to TVs and arcade machines and so on.

Can The Voltage That A CRT Tube Operates At Be Changed Without The Use Of A Transformer? ( eg 110v to 240v )​

Where do you connect 110V or 240V to the CRT Tube?

If you mean the input voltage that the monitor (tube + electronic) takes, then yes. A lot of them can be freely used with 110VAC up to 240VAC (hantarex polo). Some other model have a jumper on them to set them for 110V or 240V (just like an SMPS). An Hatarex mtc9000/900 for example, only work with something around 128VAC....
I'm sorry if I sound mean, but this thread makes no sense at all.

Just glad it was posted on April 1st to confuse matters even more

 

[eliotcole]

I don't understand ... sorry.

Plus, don't worry, can't see anything mean.

I believe that you might be trying to answer the question that I have asked, below, which was originally entitled:

Are CRT Tubes Tied To A Specific Voltage? (either 110V or 240V)​

To keep things simple ... a yes or no question:

ARE ALL CRT TUBES MADE WITH ONE VOLTAGE IN MIND, THAT BEING EITHER 110V OR 240V?

or, to put it in an 'opposite' sense:
CAN ANY TUBE TAKE ANY VOLTAGE?​

If the answer is 'sometimes' or 'it depends' regarding whether they are tied to a specific voltage then that answer is classed as 'Yes, they are voltage dependent' ... if there is no situation where the voltage matters in relation to the CRT tube, then the answer is 'No' to this particular question. 🙂

I would assume that one would need to ensure that a tube can take a certain voltage.

... all of which I acknowledged before any responses had been made to this question with the second post, quoted below for the record:

I think the main confusion here is Calling a Video Monitor a CRT

So far established, CRT Tubes DO care about Voltage as many different Makes, Sizes and Models
Monitor Chassis DO Care about Voltage input because some are tied to 110v and odd ones 240v but some may be switchable like Jamma PSU

And finally what advantage is it trying to alter the working voltage of a Video Monitor without using Transformer? which is safer than live 240v powered chassis

The fundamental basics parts that make up a Video Monitor is quite essential in some cases

This, also dont some arcade monitors require the use of an isolation transformer as well. Remember talk of it a long time ago but cant remember what the reason was that some monitors needed an ISO transformer and others were safe without.

 

[Georgian2]

Well, the gearbox in your car dosen't care if you put petrol or diesel in your car. The engine dose. The engine must output whatever the gearbox is made to accept as input.
