okay students, today we have a Hartke HA3500 bass amp that sounds great, puts out lotsa power, but when I run it into a load it overheats and shuts down....then it cools and the output kicks back in...then it overheats and shuts down and.....well you get the idea....
from what I've found on this here internet thing is this happens alot with these, and nobody knows why.
what do you all think?
shall I lower the bias to the output transistors....I'm loathe to start playing around with it....
any of you smart guys work on these?
