Nice 300B tube integrated amp. Good startup protection circuit, which keeps the outputs off for nearly a minute as the tubes warm up. Tube complement:(2) PS Vane ECC82 (12AU7)(2) 6H8C (Can also use 6SN7 and 6N8P) (1) 5Z3PA Rectifier (Can also use 274B and 5U4GB) (2) PS Vane 300B Very nice sound and surprising good looks. Quite the conversation piece! Some of the other Yaqin 300C amps have some really bad graphics on the top of the output transformer covers. I was pleasantly surprised to find these to just be black. Includes the power cord, manual, and remote control. Also including several NOS tubes to start your tube rolling journey. Including (4) GE 6SN7GTB and (1) Phillips JAN 5U4GB.

Too much blood, sweat, and tears invested in the Elekit to not use it as my daily driver. However, the Yaqin is much more to look at for sure. NOTE: You will need a long reach 2.5mm hex allen wrench to remove the tube cover. Should be able to find an inexpensive one on-line. I have a compete set of long reach metric allen wrenches, and didnt want to break up the set.
