- My VOX AC30 C2 amp was picking up all kinds of radio sounds. It was as if I was listening to AM radio while I played the guitar. I changed out the 4 power tubes and replaced them with EL84 Groove Tubes and the problem is now fixed and my amp sounds better than ever!. Hope you enjoy.
Good idea to not touch the tube with your bare hands. The oil on your fingers can shorten the life of the tube.
That's true. Thanks for pointing that out. I appreciate it.
Hey these Video is very exciting and helpful. Bought the AC 30 C 2 few days ago, very excellent and great Sounding Amp with great History. But th e next step i'll do is to replace and change the China-Tubes against much better Brand-Tubes. Thank you for this nice lesson. Best regards from Germany :-)
Thanks for the comment. Glad you enjoyed the video. The tubes make a world of difference.
Hey man, I know it's been a while since you uploaded the video! But, I was curious to know - do you need to put those metal wires around the tubes again? If so, how would you go about putting a tube damper on them? Thanks so much if you do see this, this video was so helpful for me!!!
Can somebody help, my ac30c2 is leting out some wierd hum, tremolo like, is that normal? Its my first tube amp so I don't know..
Great video man! Waiting to see if can do this when i get home. Mine is the Vox AC30 S1 and im getting some nasty noise when the amp gets hot, it only goes away turning down the volume and then i turn it back up and its gone only for a while. Im wondering if its the power tubes?
I have the same amp. I noticed it make a high pitch buzzing noise if I leave it on for a long time. Have you figured out anything?
I could replace the tubes in anyone of my Fenders without a screw driver, but Vox and Orange make ya work for it lol ! Luckily my Orange and Vox have never needed a tube changed during a gig.
9:30 I like that little car in the right bottom corner
Thanks. In almost all of videos you will find a VW bug
An amp tech on line noted that on a Princeton top inside back panel was a strip/sheet of aluminum
foil affixed that was used to help eliminate radio transmissions.

Few minutes one hand
Nice one man! Out with the China, in with the Groove!...lol..!
Cheers for the video mate, my amp has been picking up some stations too haha !
rebias?
The Vox AC30 is a cathode bias design. This means the tube itself sets its own bias.
@@NothingButFuzz tks!
I can’t even get the back off my AC30!!
Had the same problem. It's a little sticky. I needed to pull a little harder because it has probably never been taken off since it was build. I was afraid I might damage it, but it was no problem. Just make sure all screws are really driven out.
@@TheAbrissbirne thankfully I got it after a lot of tugging. Thanks for this message
oh no the amp doenst work
It does now. Lol. Time to crank it up to full volume!
I replaced my valves with JJ’s ordered through the internet
Awesome. I'm sure the JJ's sound great!
How often should you replace the tubes, based on normal usage…. Daily for about an hour ?
