Members jjang1993 Posted August 12, 2016 Members Share Posted August 12, 2016 Hi everyone, I just have a quick question. Have any of you guys had trouble with Groove Tubes or Electro-Harmonix 6V6s? I've gone through 3 or 4 sets since April (each set developed microphonics). I bias them cold in my Fender Super Champ XD. I'm just wondering if I'm the only person having problems with Groove Tubes 6V6s power tubes. Link to comment Share on other sites More sharing options...
Members mrbrown49 Posted August 12, 2016 Members Share Posted August 12, 2016 I've been following your other thread. It's the amp, not bad tubes. Time to bite the bullet and bring it to the amp doctor. Link to comment Share on other sites More sharing options...
Members thatsbunk Posted August 12, 2016 Members Share Posted August 12, 2016 What mrbrown said. My prri is about 3 years old now & is my amp that gets pushed most. No issues. Never even looked but I assume they're stock groove tubes. Link to comment Share on other sites More sharing options...
Phil O'Keefe Posted August 15, 2016 Share Posted August 15, 2016 I've got GT's in my '83 Princeton Reverb II and they've been going strong for quite a while now. No issues. Link to comment Share on other sites More sharing options...
