Up for sale is a Willsenton R300 amp based upon the legendary 300B tubes.

At $1000 this is one of the best values in tube amps period. I'm not aware of any other 300B based amp that's this cheap. This amp is well regarded for it's very musical and pleasing sound as many 300B amps are. Check out some reviews, they're all glowing.

At 8 watts per channel, this will drive high efficiency speakers well but I found that it's also excellent for headphones. Smooth but also very dynamic with all that power on tap.

Price includes PayPal fee but not shipping, that will be calculated per person since it's quite heavy and shipping cost will vary.
