I have for sale an 1964 Ampeg B-15N with mostly original internals. I sent this amp to Bruce at Fliptop Amps in NYC. He went through it and changed a couple of capacitors, added the Ampeg logo and light and a 3 prong plug. I also commissioned him to make the repro cabinet which sounds amazing! No rattles! The cab comes with an early 60's CTS speaker. I simply have too many amps and need to part with a couple. I can provide a sound clip of the amp upon request. Unmistakably B-15!!
