mc2102 kt88s
i just bought a mcintosh mc2102 tube amp, this may be a silly question but im fairly new to tubes so bear with me.
the question has to do with the coloration of the tubes at different volumes, the more power i use the more the kt88s glow blue.
at around 80 watts the blue hue is very intense & seems to follow the beat of the music, nothing like blinkin disco lights, subtle but noticeable when im lookin for it.
ive owned several tube amps in the past & never saw 88s do this.
even though the amp is new & under warrenty im a little worried,i love the 2102 & dont want to continue listening to it if there is a problem in the kt88s that may lead to damage in the amp, am i overdriving the amp or somthing.
