marrk	Re: Modification for Mesa Boogie .50 Caliber You may be right. Esp. since you have had a tech go over it. Maybe try R.G.'s tube amp debug for some ideas. You can also check that all the wiring to the pots/switches is done correctly or not cold jointed. I just thought of something. Try sending the preamp signal out to a different amp. Then try sending a signal into just the .50 power amp section. This might help locate which area the trouble is in, and save some time. The last resort may be to just go through the amp from the input jack, through the entire circuit. This will be a time consuming task. Let us know how you make out. Mark
