    Have you tried cleaning your volum knob it kinda sounds like the potentiometer might be dirty

    Tubes are unlikely to be the issue, sounds to me like a dirty volume pot. This is a cheap amp, and so I don't expect they're using anything fantastic for a pot - it's probably carbon.

    It's possible you have a microphonic or noisy tube, but that's much less common. Gently flicking the tube should give you an idea if you've got a microphonics issue or a dirty tube socket / cracked solder joint.
     
    90% of what gets perpetuated online about "tube quality" is crap. By far the most problematic tubes I encounter are old American tubes (both NOS and used). The NOS ones have been sitting for so long that many of them don't have a clean vacuum anymore, and if you don't recondition them, they arc. Reconditioning tubes is a whole topic to itself, and the process varies significantly depending on the type of tube - reactivating a 100 kW klystron or a 4CW10000A is a whole different ball game from reactivating an 807. 
     
    If you end up replacing the tubes in that amp, go for new production.

    hi there,
     
    doesn't sound like a tube issue to me - Tubes should last a decade before they start to sound worn out. - Unless you use that amp 7 days a week for 10 hours a day.
    Also "static noise" doesn't sound like a tube issue.
    Here is what you can do before considering replacing the tubes.
    Check the amp on a different power in your place. Even check at a friends place.
    Maybe some other stuff in your place provides the noise. Often cheap power supplies are able to pollute the whole circuit. So try to shut down everything but the amp itself.

    Also try contact cleaner for the Volume-Potentiometer. Like Deoxit F5 or CRC QD Contact Cleaner.
    You can test if the Volume Potentiometer is the issue by moving the knob all the way up and down for like 50 or 100 times. ( w/o headphones attached - you don't want to kill them lol ) If it gets better, get the contact cleaner.

    This era of computer hardware is nuts from a consumer perspective. This is my micron transport XPE from 1997:

     
    This has a 166mhz Pentium MMX, 48mb of ram, a 1.1gb hard drive, floppy drive, cd rom drive, and an 800x600 display. Runs windows 98
    This machine specced as it is (with the exception of windows 98) would have cost around $3800 USD in 1997. That is over $7000 in 2022.
    And within 3 years this was showing it’s age heavily as the later Pentium 3’s and such hit 1ghz, ram went from sub 100mb to 128/256mb being common, 1gb drives to 20-40gb drives.
    And 3-4 years after that this machine was nearly unusable, entirely outclassed in every way, Pentium 4’s at 2ghz+, 512mb to 1gb of ram, etc
     
    Imagine if you bought a $7000 laptop 6 years ago, just 2016, Skylake era hardware. Like an i7 6700HQ and 16gb of ram with a 1tb nvme ssd, and right now that machine could barely function with modern demands and current gen hardware made it look like a toaster.

    Yeah I tried it and as soon as the monitor turned on it only survives like 0.5 seconds before dieing... Thx tho... If you have time could you help me find a replacement with this kind of connector online? (In the picture they're two separate of the same one not a one connector)

    NystriX reacted to WereCat in What's the difference between a power brick and a power plug?   
    The output voltage may be the same but the current is way higher with the brick on the top picture, meaning it can handle way more power than the bottom one. 
     
    The bottom one is only 12V 2.0A so max 24W output. 
    The top one is 12V 4.16A so 50W output.

    NystriX reacted to Spotty in What's the difference between a power brick and a power plug?   
    The wall plugs tend to have lower output. That one is 12V 2A (24W) max output while the power brick you are trying to replace is 12V 4.16A (50W). To replace it find a power brick that has a 12V output voltage with a max current output of at least 4.1A.

    NystriX reacted to Kid.Lazer in What's the difference between a power brick and a power plug?   
    If you look at the output ratings on each of those power adapters, the smaller one is rated for just about half the amperage. So, no it would not work in this case.
     
    Also, make sure any news one you intend to buy have the right polarity. Your old one is positive on the center pin and negative on the outer ring.

    You can simply boot from USB stick and install any Windows you want. 
     
    They ship it with FreeDOS because it's open source and free, so it works around some legal requirements in some countries, which force Asus to ship laptop with an operating system and for laptop to be "ready for use" (you can show it's working by typing some dos commands) 
     
    So you can use a usb stick , or a USB cd/dvd/bluray or boot from network if the laptop has network card and install windows or any linux or whatever.

    The better option is usually to use string resources and specify the title in your manifest instead of through code.
