The Yamaha B2 is a highly regarded amplifier, yet we're confident you will not find an example better than this. After a complete rebuild, we can't imagine new old stock would test better. Delivering 100 crisp, clean watts, and featuring two beautiful meters, this Yamaha B2 looks and sounds like it was delivered from a time machine. Absolutely superb.
