[QUOTE="retropete, post: 135985, member: 3334"] Hi all, Last night my Lynchbox was sounding spongy... and then I started getting microphonic squealing and kind of a clicking sound when I was running at high gain. And this happened regardless of which module I was running through. Does this sound like it might be time for new power tubes? I've always had a repair guy replace my power tubes with other amps but I understand it's supposedly pretty easy with the RM100. Do I need any special equipment to rebias? I'm using EL34s now, I think for this go round I'll probably stick with them, but I'm interested in trying some of the other configurations that others have talked about... KT88s for instance. What do you guys think? Peter [/QUOTE]
