The amplifier is defective but still works but there is an issue where sometimes sound will only play out of one ear. Unless sound is turned up really loud then it like “wakes up” for the other ear. I purchased another set up tubes and the problem still persists. The amp is out of warranty and I didn’t want to sink anymore cash for the inspection and repair so I just bought a new amp instead. Maybe you can figure out the issue and get it fixed but I don’t have anymore time to tinker with it so going to sell it off instead. It comes with all cables and will be repackaged with the additional tubes I bought!
