In Reply to: Can someone explain why a thermistor is used in an amp's power supply? posted by Norm on March 18, 2012 at 10:05:17:
I used to use an amp that had thermistors to limit current on start up. The only time I had them pop on me was when the unit powered off and then back on too soon - - in this case, the thermistor is still warmed up, and it doesn't limit the current well, so too much hits it and fries it.
This happened to me once when I had switched the amp off, changed cables and switched it back on. Poof! A lasting lesson. The only other times were when our neighborhood experienced brief power disruptions. PITA, to say the least.
