I bought this China clone "Marantz-7-M7-Tube-Buffer-Audio-Preamplifier-Pre-AMP-Board-KIT" I thought that it was just simple. I just don't want to throw it away, but what does 220v mean input meant in this? Does it go straight to the utility power? or is there a 220v in and 220 out transformer?????(Is this question stupid?)
This question is also about sound quality too? so please give me some advice how to power this properly.
