BBAmp (BeBamp) bread board tube amp with no driver stage.

I wanted to see if I could drive a SE UL tube power stage from a two stage tube preamp. This bread board amp (BBAmp - BeBamp) was constructed to test the theory. Most bread board amps have the wiring exposed. I wanted this to look and sound excellent so all wiring is underneath the bread board. There are lots of exposed components e.g. rectifier components, but all wiring is hidden. The bread board is Australian pine, sanded and treated with Australian beeswax. Edcor OPTs are enclosed in the aluminum case (back right) which provides a back plate for speaker posts and input RCAs. The amp is absolutely dead quiet and extremely transparent. The amp will produce the sonic signature of your preamp. A high gain preamp and very sensitive speakers are required. This can be shipped as a modular bread board kit amp. The tubes are JJ Blue Glass KT88.
