So my much loved tube preamp (VAC Standard) suddenly is not playing in the Left channel. The tubes are five years old, and I was leaving it on 24/7 for at least four years, until it was making some small 'tubish' gurgling noises (which stopped if I turned it off at night. Meaning even when on, no noise, IF I let it set off each night) So I figured on of the tubes finally decided to die. I did not change the tubes back. They lasted a longtime anyway.. Whoo Hoo. The moral of the story is I am getting old and decrepit.. I need to pay better attention to what needs to be checked BEFORE I start swapping in new tubes. Oh, yeah the new tubes sound pretty good. |
