No affiliation, just looks to be a good deal if looking for a Williamson amp. If I were not starting my own build, I would snatch them up. It is a local seller (maybe a member of this group?)

Those are nicely restored. For those who don't follow Dave Gillespie's Audiokarma threads, he has vastly improved the performance of a series of Heathkit amplifiers. While not the crown jewel of the Heathkit W series, the W4s are lovely 20wpc Williamsons. If you think SET is the be-all, you should hear a well-tuned Williamson. 
Gillespie made some subtle changes, and installed a multi-tap feedback network to ensure smooth performance and stability on all taps. I myself have rebuilt a pair of W4s to his specs and they're mighty close to my Peerless Williamsons, for a fraction of the price. For $600 and local pickup, these are a steal, IMO. Install some premium NOS 6SN7s and a quad of Gold Lion KT66s and you have some really beautiful amps.
