Adcom GTP-500 II
Hello, all. I have the subject audio preamp/tuner that I purchased way
back in 1991. It has worked flawlessly over the years but yesterday started randomly power cycling (the unit uses a relay) without operator intervention. When it's on and feeding the companion GTP-500 II audio power amp everything works audio-wise except that in addition to the power cycling, infrared remote control has also been rendered inoperative. Has anyone seen this or similar behavior in other products? I currently do not have the service manual. I did unplug the unit from the AC line for 24+ hours but upon restoring AC power the problem continues. Thanks for your time and comment. |
