Saljam Posted April 24, 2010 Share Posted April 24, 2010 Hi guys... I'm hearing some slight static on my Valve Sr. This thing has not been used much at all and never pushed too hard. I've tried different cables and its still there.. Any ideas what this could be? Thanks Link to comment Share on other sites More sharing options...
Dennis G Posted April 24, 2010 Share Posted April 24, 2010 OK, spooky. I was playing a couple of weeks ago and noticed what I thought was static as well. Changed a few settings, no diff. Changed guitar and cable, same thing...hmmmm...Came back next night no problem, and no problem since. As above, pretty much home use, not overused and/or abused, and probably 50 hours max.

Tragic1281734187 Posted April 26, 2010 Share Posted April 26, 2010 When I think of static, I think either a tube possibly dying, or a Cap or resisitor charging . My old Tweed amps and blackface amps do this when I have not played them in a long time. Leave the amp on for a couple of hours. If the static is is still happening, tap the hot tubes with a chop stick. That will lead you to a faulty tube. Hope this helps. Link to comment Share on other sites More sharing options...
m-theory Posted April 26, 2010 Share Posted April 26, 2010 It's a microphonic tube, almost certainly a preamp tube, and very likely V1. Tap lightly with a chopstick or pencil while the amp is on and you'll be able to identify the culprit. Link to comment Share on other sites More sharing options...

Saljam Posted April 26, 2010 Author Share Posted April 26, 2010 Problem solved.... I dont know what it was but no more static. It was strange man... It was slight but every time I hit the strings it was present. It's back to smooth sailing now. Thanks for the response! Link to comment Share on other sites More sharing options...
m-theory Posted April 26, 2010 Share Posted April 26, 2010 It'll come back. It's almost certainly a microphonic preamp tube. They often do this sporadically at first. Link to comment Share on other sites More sharing options...
