These are Vladimir Bazelkov's famous 6AS7 based parallel SET amps. If you have efficient to highly efficient speakers, especially if you have horns, these are exceptional performers. If you take cost into consideration, they have no equal that I am aware of.
I am the second owner. When I bought them they had been treated to a cap mod with Janzsen Superior capacitors installed. However, after about 6 months of use, one of the amps stopped working. I contacted Vlad and he told me to send it to him. He contacted me about a week later and told me that the mod job was the problem and that he had cleaned it up and the amp was like new. He then insisted that I send him the other amp since it was probably just as sloppy. I did so, and he sent them back to me. All I paid was shipping.
That was at least two years ago and the amps have been boxed in my garage ever since except for a brief audition soon after I got them back. My system is a two channel theatre/entertainment center and it is on 15 or 16 hours a day. It just didn't make sense to burn tubes and generate heat like that so they went into storage.
Along with these amps, I can provide at least a dozen extra output tubes and a spare set of input tubes as well.
For any of you who like to work on your equipment, here is a guy in Denmark who outlines the mods he's done to an identical pair of amps.

I'm asking $2100 for the amps and all of the tubes. This includes shipping to anywhere in the lower 48 states.
