Hi guys!
A friend of mine bought it used....
He complains about:
01- Switching noises when engaging thru different channels...LOUD POP thru speaker cab;
02- Loop FX seems to be crazy...alters from soft to stupid levels without any change..gremilins inside? :dontknow: :laugh:;
03a- He was playing a gig on Saturday nite and got a LOUD thumb from speakers...looked to amp and it was dead :cussing:;
03b- Mesa calls for 4AMP fuse, he finds out there was a 8AMP FUSE inside.... :cussing: :cussing: :cussing:;
03c- 1 out of 6 power tubes is shot - getter turned white - happens to be a center tab - aligment pin - which is missing :w2:;
03d- There are 3 Rectos (5U4G labelled MESA), one of them is also shot... suicide note: he never plays on hollow state rectos...
So he brought it to me...I did not have time yet to open it. I would like to ask you guys whether you have a schematic to share....
Many thanks in advance...
Best Regards
R.
