Up for sale is a very cool 1957 National Tremtone amp. it features (2) 6X9 speakers being pushed by (2) 6L6 power tubes. The amp is in good shape, gsome gdusting of the corners and a small hole in the grill that did not effect the speaker. It still retains it's original transformers and most of the circuit. It has had a service, so some caps and the cord were replaced, but ar included with the amp. The amp plays and sounds great, and the tremolo works great as well. If your looking at the ad you must know how cool these amps are, and what a good investment they've become.
