This is a fabulous sounding LA2A rework by Dripelectronics. He printed a PCB, which has everything on board except the heaters and hookups for the transformers - much easier to build than the point to point version. I used Sowter transformers, and they sound great. The meter is something I was given by a friend of mine - notice I had to add a little germanium rectifier on a breadboard to make it function properly. The TB4 is an original from the JBL tent sale, and the aluminum case is from par-metal.
