I just received the new version of the Glowmaster with a pcb and auto bias circuit. I must say it is a glorious sounding amp. It pulls you into the music, revealing and alive. Likely the best amp I have owned. I will comment that it has a high noise floor, there is a hum coming from the amp, tolerable yes, but it is there and noticable.
Has anyone else experienced this? Solutions? Different tubes?
