Greetings Everyone,
I have an old Fender Deluxe 112 Plus solid state amp (type: PR291, Serial: LO-674886). Been sitting in the garage for a few years. Want to give it to my son, a 9 year old aspiring rock and roll guitarist. It used to sound good, but now the sound is mostly midrange/treble. I do hear some low end if I crank the bass knob all the way up. The shrill sound goes to the bone!
Don't want to toss the amp and could use some help locating the root cause. I already inspected the circuit board and did not see any burnt components. I also re-soldered every connection...no help. I'm thinking the next move is verifying capacitor values (non are physically expanded or leaking). Any other advice? I'm an engineer, so electronic-speak is not a problem.
Does anyone have a schematic for the amp?
Thanks in advance!
