It was made some time in the 1970's by a Greek audiophile who made several variants of these amps. Two of these amps where brought to the US by a Greek diplomat. One set is a four chassis monster and the other is a two-chassis monster. I believe both put out about 30 watts but they sound much more powerful. The amps are based on a Futterman circuit. Each monobloc has a massive toroidal power transform and essentially two smaller amp modules (smaller toroidal power transformer and set of tubes) that are either bridged or in parallel. I forgot what kind of tubes are in the output; they are some kind of television sweep tube. The tubes are run very conservatively so they last a long time. The previous owner left the amp on essentially all the time for the past 10 years and the tubes still test as good.
The dealer which who recently got the amps in trade for some speakers wanted $50k for the pair of amps.
