Offered is a Yamaha power preamplifier B-2 in good condition. The quality does not need to be explained: design, implementation and musicality are of great class. Copy of the original receipt, as well as user and service manuals are included. There are some modifications carried out. The power switch and the speaker relays are renewed and the speaker connections improved. The input selector button is broken off; the B2 now works only through inputs 1. At the speaker selection switch a couple of components have been removed leaving only speaker connections B to function. The removed parts are included. If inputs 1 and speakers B are used, the B-2 works like in the old days. Power output: 100 watts per channel into 8Ω (stereo). Dimensions: 436 x 370 x 151mm. Weight: 26 kg
