Selling my WA6 with Sophia 274b. I've replaced the other tubes as the ones that came with it started buzzing. The new pair sound identical to the old (without the buzz of course!). It is in mint condition, no scratches, no scuffs. It will come with the stock rectifier tube, and in the original shipping box. This amp is dead silent with IEMs or other high efficiency headphones; no hum, no hiss, no buzzing. Many people enjoy it at meets I've taken it to, and it doesn't sit unused for long. Price includes shipping. US only.
