Ive had 3 6505's thru repplacemnts. At this point i dont think its any better quality than the bug.
Same here, mine was more time in tech service than in the rehearshal space.
At first it kept blowing the fuses, then the power tubes, then some dodgy resistor in the power stage...sounded great, but it did last 3 months before next service ( I kept it for 3 years)
