My funniest moment (not at the time) was when I hooked up a new pair of interconnects from my preamp to my tuner. I couldn't wait to hear the difference from the old interconnects. I, patiently, warmed up my tubed gear for about 10 minutes and left standby mode, but when I turned up the volume, there was no sound at all! I was beside myself, when I discovered that I had mistakenly hooked up the interconnect on the aux line outlet instead of the tuner line outlet of the preamp. Since the source selector on the preamp was set to tuner, I got no sound. I guess I could have switched the preamp source from tuner to aux and listen to the tuner, but instead, I turned everything off and installed the interconnect to the tuner outlets of the preamp. It was a very frustrating 30 minutes before I got everything right. I am glad I was alone when this happened. I have had other senior moments and am a master at misplacing my house keys. At least, I found the new interconnects pleasing!
