We had built the most powerfull single ended amplifier with ONE only ONE powertube, which is alone on the market, and NO other builder makes the same! If you know other same 65 watts SingleEnded amplifier, PLEASE share with me.
The GU 81 SE's building job took a lot of time, it need 2x8=16 different designed/calibrated transfomers (OPT, Power, Filter Choke, 600ohm, Interstage), separate powersupply. The 2x2 pieces chassises are cca 100kg total weight, and it looks like a power station -anyway it is- a high power Single Ended tube amplifier, which could drive Electro / MagnetoStatic speaker too.
power: 65 watts
ask me about the price
