How do you change the valve/vacuum tube?

I had been wondering this as well since the manual makes no mention . But , it seems that the amp chassis needs to be dropped to access the tube . There are 4 screws on tabs that drop from the chassis itself, inside the cab. . As well , it may be necessary to take out the 2 screws that line up with the chassis that are in the Tolex covering . Obviously , make sure the amp is unplugged before starting any of this . Hope this helps . Might call Bugera cust svc too . LMK . Im curious too .

All you need is a Phillips screwdriver #2. Set the UNPLUGGED unit on its' face, handle towards you. Remove the four black screws on that secure the black amplifier assembly into the wooden frame (inside, along the sides). Now loosen the four chrome plated screws that are not part of the corner guards or handle. They have raised little aluminum collars beneath them. Now you will be able to gently work the amplifier assembly out, being sure not to yank on the speaker wires. Access to the tube is from the side, beneath the Input jack, and a spring holds it in place. Most bad tubes won't glow; the filament is fragile, and wears out over time. Good luck!

Also, beware that tube amps will hold a significant charge long after the have been unplugged. Sonds like this only has a tube in the preamp stage, but be careful!

Why? You shouldn't need to do that, if so im sure it's not difficult or you could take to music tech. I turn mine up to 10 and no problems, except needing ear plugs, lol.

I never used mine because it's a sweeper not s vacuum. Watch a YouTube video on setup and it shows how to adjust the valve

There is a small black piece that you flip so that it is compatible with both types of tube valves. It is inside the opening after twisting off a metal piece that holds the plastic piece in.

Don't think so. U might be able to remove the release valve. And replace it with the giggler valve. Then u could use this giggler/w the new valve.

You can do a hack and replace the valve that comes on it with one of these. Works awesome for me.Michelin Avenir Dual Head Replacement Bicycle Floor Pump Hose

take the screws off and and cover plate clean the inside. lube up the o ring. if the screws are stripped you might have to replace the valve. these valves do have a lifetime warranty. but they only replace the insides. like I say if the screws are stripped you will need to replace. and it's a pain.

Had the same problem when I got it, not knowing how to change it to work on a Presta valve. The pump works for standard inner tubes when it arrives, so you need to change the adapter on the end to work for Presta valves. It is really easy to do. You can remove the cap, and just flip over the little plastic piece that accepts the valve stem. If you can't figure it out, visit the manufacturer's website - they have very clear instructions on how to do this.

YouTube if you need to, it's pretty self explanatory. Drill hole with step bit, then put kettle between two gaskets on the back side of the valve and tighten everything up. Easy install took me 5 min including drilling hole.

That's difficult, it's just the valve. We bought a cheap plastic one, then hose suction cups, they work alright

You replace the one tube with the other. You should have the instructions in the box. If I had access to mine right now, I would tell you exactly. I know it took me a while to get it. It works great though

There is a picture on the side of the vacuum. It's tricky and you need the tool to grab and twist it on, but it can be done. Hope that helps.

Either try using a razor blade or sharp paring knife. Look at one of your other valves and make a copy cut on your unslotted valve. Second option, contact Camelbak, they have an excellent customer service process. Based on my experience, I wouldn't be surprised if they didn't resolve this for you favorably. Good luck.

The valve comes with a plastic "wrench" that fits into the valve to tighten it in place. A socket wrench handle fits into the plastic wrench to turn it. Very simples.

On the lower section of the valve there is a hook lever, pull that up, rotate the lower section of the valve to free it, then adjust it up or down as required. When done, rotate it back until the hook lever clicks.

I agree with you, but unfortunately I'm not aware of a suitable replacement. I would look into replacing the entire valve stem assembly -- an experienced might be familiar with this issue and have a suggestion.

The yellow tube goes into the valve by the bulb. It's been a while since I did the overhaul, but the Mantis works better then ever once you get it done. Hope this helps.

I put one in a Porter Cable. It was easy to install and much easier to use than the valve than came with it. Wish I knew if it fit your unit but I don't.
