EXPERIENCE electronics - Gegentakt-AB Monoblock mit 75 W oder 160 W

Push Pull Monoblocks

These ultralinear power amps are based on long time proven circuitries with the tubes KT 88/6550 A and EL 34. The 6 L 6 GC and similar types may also be used. For all different power tubes the same pc board fits. Only the dimensions of some parts have to be changed. The transformers have been new designed for best hifi performance. The design idea was not on highest output power, but much more on best frequency response and low distortion. The 2nd harmonic is dominating, which makes the sound close to triodes. These are the classic power amps for hifi fans in tube technology.
