Hello

A few weeks back I noticed that My Super Plexi was begginning to emit strange distortion on lower notes, and chords.  The sounds spewing forth are sort of a "sub-octave ring modulation" type sound, if that makes any sense.  They do NOT occur on higher pitched, single note playing.  I realize that this is a symptom of worn out power tubes, so I purchased some new ones, biased using the video instruction off of the Eurotube/JJ website, and unfortunately, am still having the same problems occur.  As a newb, where should I begin looking for problems inside me' amp.

Thanks

Thanks Boogieguy for your emails!  You have pointed me in the right direction towards tube enlightnement.  I'm feeling more confident in popping these beasts open now!
