Please pay attention before buying, We received feedback from many buyers, reflecting that Reisong A12 Amp have not enough power.Please confirm that your speaker is a bookshelf speakers with a sensitivity 89db or more. We don't think Reisong A12 work well with a floorstanding Speaker or the low sensitivity speakers.

Point to Point hand welding, preferred audiophiles, output transformer switch to the 76x40 higher end output transformer.

Reisong A12 Amp is an upgraded version of A10, could use more replacement models of tubes without convertor. Come with Tube Cage.
