Hey guys...I was tracking some stuff yesterday in the studio and noticed my amp was making two distinct noises (that it usually doesn't make). 1- when I was plugged into the EF86 channel and hit a low chord, there was a significant metallic rattle after the chord. You can hear it a bit when you play into the top boost channel as well. I'm thinking maybe the EF86 retainer? 2- I was playing more chords (palm mute) and realized that I was getting white noise after I played for a second. It wasn't the speaker pumping or idle amp hum, and I could could almost play rhythmically to it, just a short wash of white noise. Any thoughts? I'd love to take the amp in to get a service before I tour on it more, but time does not allow for a while. Any advice appreciated...when I get home I'm going to try swapping some tubes. Thanks for your help guys!!
