I bought my armaco variac in a garage sale for $20.its good for 20 amps and attenuates very smoothly.built it into a test panel with voltmeter ammeter and dc output as well as the 0-120 volt sockets.Its handy for first tests of projects as well as firing up newly discovered vintage equipment where inrush current can damage old discharged caps etc.you can slowly dial up the volts and watch the amperage at the same time dialing it back down if you see disaster looming.its a handy tool for troubleshooting especialy for those who take liberties with ohm,s law.
Power Up the System - What Do You Do?
I leave my system in idle when not in-use. I only kill the power when I know bad storm is comming or if I am out of town for few days. I have always disconnected my speaker cables before I start it back up and re-connected after system is completly powered up. This way the speakers don't get popped and eventually could cause damage. I am just curious how you start up your system.
Thanks.
Thanks.
