Sunbuck Direct Engraved KRELL 50W 2.0 KSA-50 Class A HIFI Amplifier

1: Ksa-50 power amplifier and KSL preamp are Krell’s classic products

2: Since it came out more than 30 years ago, it has been sought after and imitated by many enthusiasts. Pure Class A circuit, sweet tone, simple circuit and high fidelity. The circuit’s Class A power output reaches 50W, and the low-frequency control power is excellent. We carefully compared the early gold plate with the later ksa-50 plastic plate. Although the internal structure layout of the later product is more reasonable and the appearance design is more classic, the sound performance is still not as good as the early gold plate. We bought the original machine and imitated the following products according to the original machine comparison. It adopts the same wind tunnel heat dissipation structure as the original machine, and uses a silent fan made in Germany to reproduce the original appearance of the classic product to the greatest extent. The upper tube selects 15024/15025 as gold-sealed tubes, and the power transformer is two 400W ring cowls, which are the same as the original ones. The filter capacitor is American Big D or Philips BC 75v39000uf. The all-aluminum chassis is thicker and more reliable than before.

3: The KSL front stage is made completely according to the original machine, and the circuit materials are very luxurious. We replaced the original pig blood capacitors with caviar gold capacitors of the same grade. Pair the FET with the same accuracy as the original pair. The original circuit is retained. The actual sense of hearing is no different from the original machine

4: Class A power amplifier has always been the dream of primary enthusiasts for power amplifiers, because the crossover distortion of class A power amplifiers is small, even waveform distortion, so that the sound is the same as a tube amplifier, but also has the low frequency dynamics and potential of a transistor. This version of the Krell ksa50 amplifier circuit , Its power output can reach 50W Class A output and 300W Class AB output
