Due to lots of inquires from people who just want to use etracer as a digital vacuum tester we now offer etracer as a built unit. We always encourage users to build the etracer kit by themselves to get familiar with the etracer hardware but we understand it might be difficult for tubes enthusiasts who don't have exposure to electronics. The lead-time for this assembly service is four weeks. A SanAce 9S0812L411 chassis fan is included in this package. The fan is very quiet and durable.
