Hi, I started experiencing a strange problem in my RM100. It seems that the output of my preamp section is all over the place....for lack of a better term.
When i first discovered the problem, my deluxe and ultra modules would not work at all, and my xtc only had minimal gain. I removed the two inoperable ones and moved the xtc to another slot assuming perhaps it was the slots. same thing...poor output...
I put them all back in...and suddenly everything was fine and they sounded normal for about 10 minutes. I flipped the amp on standby for a bit...turned it on...and now it seems as if the gain is simply saggy and lacks any real definition. and that is where it has settled. It's been a week or two and the preamp section seems like its just flubby and weak sounding.
However, The power section works fine. I plugged my gsp1101 into the return and it sounds great.
I called Randall Three times over the course of the week, and it seems they don't have any techs available.
All tubes are relatively new with about maybe 100 hours on them. I have three tungsol 12ax7s in the head...and the stock rubys in the modules. they have more play time on them of course.
Has anyone had a problem like this?
