Quite certain this amplifier was made by Wawasee, insurance NY. At present, it is tuned for 11m. Front panel has on off, ac power indicator, and also a standby switch and am Sb selector, which adds delay, to eliminate orate least reduce, the relay chatter nice feature. Compare that to most of the great deals, from china.
Works well, and have used it on 11m Sb, easily getting 140 watts out, with nice audio uses a single 8417 tube. Photos show clean and high quality design build inside and very adequate power transformer. I am down-sizing and this neat little retro needs a new home. Tuning cap on rear disallow for band tuning, but is a bit tricky to adjust, once you set it.
