I am very new to this electronic stuff so please be gentle.
my carlsbro scorpion (i think) has got very loud. i cannot turn it up much at all, just off zero and the loudness comes, 1/4 way is pretty loud and 1/2 way is too much. what can cause this? the amp is an old one, i think 70's or 80's it has 2x12 20w celestion speakers. there are no markings on it to say which model or serial number it is. anyone got any ideas?
