Am too lazy to pull the schematic for the G-40C right now but I do warranty work for Saint Louis Music. Most problems that I see with these smaller models relate to poor solder joints, especially where the potentiometers and other front panel controls meet the circuit board. I you know what your doing you could pull the circuit board and remelt all the front control solder joints and those connecting power supply components (filter capacitors especially) and the speaker connections. Don't remember perxactly but many of the smaller crates use plastic standoffs that require compression by using needle nose pliers before you can remove the circuit board. It isn't too awful hard if you've done some electronics repair before but it does require a steady hand and skill.
