Re: Help! Repair Shop ideas or amp suggestions ... There is high voltage in a tube amp in the filter caps that is stored that can discharge and KILL you! You're looking at often 300-400 volts plus.   These caps can discharge even when the amp has been turned off for quite some time. The volts can rupture the capillaries etc around your heart and you die (as I've been informed). To work on amps, you need to know how to safely discharge filter caps.     The chopstick idea is to have the chassis opened up and the amp hooked to a speaker and have the amp turned on. The chopstick being bamboo or plastic is non-conductive. You take the chopstick and tap on various caps and resistors to see if it makes more noise or makes the noise go away. This can sometimes help isolate the problem to a cap, resistor or solder joint.     Having said that, if you are not familiar with working on tube amps.......... PLEASE send it to a amptech. The dollars to get it up and running are much cheaper than the risk of electrocution.
