Thanks, Mark at Rogue thinks the same. I'm putting back in the stock EH's and sending the NOS back for testing. The NOS was screened, a matched quad purchased from Rogue. You gotta love their customer service. Mark actually answered the phone when I called first thing today. I might try the new EH's, cheap enough.
Tubes Became Microphonic
About 6 weeks ago I put in some NOS Sylvania 6SN7's into my Rogue Magnum 99 preamp. Just today they became microphonic. Just touching the volume knob caused a metallic sound through the speakers. Tapping anywhere on the chassis did the same. Is this common? Anyone else with similar experience? Is it just a tube issue or something else? I do plan on speaking with Rogue asap but wanted advice/experiences here. thx
