So my Audio Research VT100MKII is stuck on! Switch rocks on and off but the amp stays on. Anybody else have this issue? Is there a fix without having to send back to ARC again?!! That was yesterday and it had been on since Sunday(had not realized til yesterday). Listened to music for a while last night with no problem and unplugged it afterwards. Now this morning I plugged it in to check it, the outlet sparked and the amp blew its fuse. Any ideas or input appreciated.
There is a relay RY1 contact that is in parallel with the power ON/Off switch contact. It appears the amp has a soft start up circuit. The main ON/OFF switch contact is in series with a 5 ohm resistor that helps limit start up inrush current.
