Yes it is. Just because one tube in an amp has gone down, it does not mean another tube has / or is close to. Exception: if the one tube you are replacing has a sibling, in a connected tandem-way (for example push-pull) it is best to replace both tubes with a matching pair. Check with your local dealer on this. <><><>

First of all, ensure that the power is removed from the system. Failure to remove power can cause injury or death.
Some tubes are sensitive to the oils in your hands, so you should wear cotton gloves.
After that, it depends on how the tube is set into place. You can check the replacement to find out how it's put into the machine.
If it's a plug-in type, just pull on the tube and it will come out.
If it screws into place, then remove the restraining ring and twist the tube.
If it's soldered into place, then desolder the tube leads. -----oooooooooooo------ Tubes are arranged in pre-amp, amp and power output stages. Get the right tubes. Only replace one at a time and like for like(or equivalent). Plug in tubes have 7 pin & 9 pin crescent sockets or Octal sockets (Output tubes) with a centre keyway. If output tubes are paired they should be changed in pairs Swich off and disconnect the amp. Un box the amp. You will have decided which tubes you are changing. Ensure tubes are cold. Remove metal tube covers if fitted. To prevent cuts from breakage, and to keep the tube envelop clean, wrap dry cloth around tube. With a gentle rocking motion pull the tube you want to change from the socket. Double check you are fitting the right tube. Wrap new tube in the cloth and ensuring tube pins are properly aligned with the socket, push tube firmly into place. Replace tube covers if fitted. Box it up and make noise !

How do i opperate stanby on a tube amp?
Standby is a usefull feature on a tube amp, as it keeps the tubes warm and saturated, but cuts off the output to the speaker. Standby should be used when on a break, but not as a true "on/off" switch.

How often should you replace the tubes in your guitar amplifier?
The previous response to this question "It really depends on how often you use your amp, so its hard to say" isn't terribly helpful. However, it is true that many variables affect how long your tubes will last. The first of these is how much you play and how hard you push the amp. Also, it is VERY important that when you start up a tube amp, you leave it on standby until the power tubes are warm-- usually about a minute or two-- before you start playing. This is probably the key practice in making your tubes last! Not to be too obvious, but if a tube dies completely, you gotta replace it. And, If you are not sure how old the other tubes are, for instance if you bought the amp used, replace the others of the same type as well, meaning the other power tubes or the other preamp tubes, so you have a clean baseline for future maintenance. When one goes, the others are usually not that far behind anyway. If you don't want to replace all of the tubes: If you look at your manual, the manufacturer will generally tell you what the tubes in different positions do; if you are having trouble only in the clean channel but not in the overdrive channel, for instance, you may be able to figure out which tubes need to be replaced from that. Signs your tubes may be going bad include: 1.) Less output than you are used to, or output that fluctuates without you touching the controls. 2.) High pitched squealing, especially in the gain channel. This usually indicates a tube that's become microphonic and needs replacement. 3.) An unusually high level of hiss or hum, more than typical. 4.) Tone pitch oscillates up and down 5.) Amp blows the power fuse frequently. This usually indicates a hard short in a tube. 6.) The color of the light from the tubes should be a dim orange and the output of all tubes should be even. If you have one tube that is brighter than the others, or tubes whose output is very low and blue-colored, you need to change those tubes. 7.) The glass bottle on a healthy tube is clear. If the tube has a whitish color to the glass, or if you see granular particles inside the tube, it is time to replace the tube. Warnings: Unplug the amp before doing ANY maintenance. Your amp has large capacitors in it, and it can give you a serious or fatal shock even when it isn't plugged in. Leave the power switch OFF and the standby switch to ON to dispel some of the cap voltage. This will not fully discharge the caps, so be careful. When inserting tubes, only one hand should ever be touching the amp at any one time. If it helps, put the other hand in your pocket! If you need to do anything more than change the tubes, the amp needs to go in the shop. Your life is worth more than the bench fee. When changing tubes, never touch the glass with your bare hands. The oil from your hands will damage the glass when the tube heats up, and shorten the life of the tube drastically. Use rubber/ latex gloves or a small piece of newspaper to hold the tubes while you plug them into their sockets. If you do touch the tube with your bare hands, wipe it down with alcohol and let it dry before turning the amp on. Wail On!

You need a cabinet with a tube amp or you will potentially damage/destroy the power tubes and/or the amplifier.
Can converter tubes found in old radios be used to power a homemade tube guitar amp I found that most are more complex than your average tube but I can't find a comparison of the difference?
Probably not. You need to get the tube number and replace with the same tube or a functional equivalent. If you get the tube number and post a question here, someone might be able to locate a source for you to find the tube you need.
What is an amp tube?
An "amp tube" is more appropriately referred to as a "vacuum tube". It is a very old analog technology that is used on earlier electronic amplification processes. Tubes are generally favored higher than their digital counterparts in the guitar realm due to their tone. Their tone is more lively and complex than the dead, flat sound of a digital amplifier. Generally tubes are wired in a series, each amplifying the signal. The greater the wattage, the more tubes are needed.

How do you play your tube amp Clear at loud levels?
The main reason people buy a tube amp is for the power tube distortion. A lot of people look for lower wattage amp (between 1.5 and 15 WATTS) so when they turn it up louder they get the natural tube "mud" on the sound. If your amp is beginning to distort or become muddy at higher volumes then you are pushing your power tubes. This will not damage the amp but it may damage your sound. I recommend buying a new amp with a higher wattage rating. This extra "head room" will give you the ability to play louder without distorting.
