Hello,

I've been doing some research on the best way to drain the voltage from my Ampeg vh140c solid state head. I am fairly new to the amp repair game and would like to know the best(& safest)  way to drain the power supply on this amp specifically. I've grabbed a copy of the schematic here

Am interested to know if this unit has bleed resistors already installed or do I need to make a discharge tool? Also how well does the method of hooking up a guitar and playing it as you disconnect the unit from the power source work?


Thanks in advance for any advice!
