Hoagie7 2 Posted October 8, 2013 Ok. I have the popping, crackling noise, so I'm doing the tube change to JJ's.I've removed the back panel, and the four screws from the bottom , but the chassis is frozen in place. Tried a little force, but afraid something will break. Shouldn't the whole thing come out the back by pushing the front? Anyone with experience here would be appreciated.

TheRealZap 7,366 Posted October 8, 2013 the line6 service tech does not recommend changing tube brands... for details see: http://line6.com/support/topic/2998-is-it-a-tube-problem/?do=findComment&comment=20304 Quote Share this post Link to post Share on other sites
geekpimp 10 Posted October 8, 2013 I think you also need to remove the screws in the handle. Quote Share this post Link to post Share on other sites
Hoagie7 2 Posted October 11, 2013 Thanks for the input. After looking it over one more time, I took a metal putty knife and wedged it under the chassis and broke the glue lose that was holding it and finally got it out. So just 4 screws on the bottom and glue from the covering held it in tight. Replaced all the tubes and bias and now it's better than ever. It even sounds better through the HD 500X now than it did before. Oh yeah, the crappy stock tubes where the problem. The one in V3 blew before I could remove it. Read where others had the same problem and re tube fixed it. Been playing for over 25 years and this is the best sounding amp I've owned to date. Love playing through it.

Brazzy 440 Posted October 11, 2013 Sounds like it was a success. Try to let us know how it holds up in the long run. Quote Share this post Link to post Share on other sites
