Ok, I am not sure where I can find info on this little internal Bazooka bass tube amplifier (elahp3.2) but I really would like to attempt to fix it. Am I posting in the correct thread? I noticed that there are some heat spots on the circuit board and was not sure if the negative is supposed to look like this? I also do not see any popped caps or diodes. Here is a picture, is this an issue?
