First try swapping the tubes from side to side. If the buzz switches sides best bet is a defective tube. If swaping tubes did not help, swap the speaker cable leads from the back of the unit. If the buzz does not switch sides, you may have a speaker problem.
Loud hum/buzz from my left speaker only
I just received my hf-81 and just got done hooking everything up. Okay, I'm only hooking a CD player to it via the AUX A inputs on the back. I'm very clueless when it comes to tube gear so I really need your help.
I've got a very loud hum/buzz coming from only one of my speakers, the left one. The right one seems to be fine. I've tried plugging the hf-81 directly into the wall, which is on a grounded hospital grade outlet and into my topaz ultra isolation transformer. Either way, I still get the hum/buzz.
Please help me,
Mike
