So, I've got this beautiful unit that I've recapped and relit; but, with a sledge gut problem. It seems to go 0-100 on the volume. As in it is very loud and 9:00 and ridiculously loud at noon. I've tried all kinds of different inputs in all the different sources and still have this issue. Is this how the amp is designed? Just seems like no headroom or space for enjoyable listening levels.
