Excellent tube amp. Bought this NEW 4 years ago. It was kept in a warehouse for a few years by the seller who was the owner of an audio store. Low hours on the original 6550 tubes which produce tight deep bass. Note this is the factory SE version, not modded from MV-60 which uses the EL-34 tubes. The model no. on the back says MV-60SE. 60 watts/channel. Comes with tube cage, long plastic screwdriver to do bias adjustment which is really easy. Also has the original box, manual and warranty card. Price reduction!
