The excellence of the Swiss Gaowen amplifier is evident, with excellent analysis, detail, and air quality. The circuit input has a single differential structure, and the input and output terminals of the circuit use field-effect transistors. The vocals are made very delicate. We have done this circuit before, but when the 2SK170 was discontinued, we couldn't continue working on it. Later on, we found Toshiba's more outstanding Rongsheng 2SK series venue, which has better consistency and even eliminates the need for debugging at the midpoint.
The original output tube is Hitachi 2SK10582SJ62, and the parallel connection with low output current has already skyrocketed in price. The kit now uses classic European and American high-power output tubes K9240 and K240 instead, with higher output current and better control.
The circuit materials are of high quality, with NOVER gold filter capacitors and all tubes made of imported original transistors. The resistor is from the Beijing Copper Pin 718 series, and the feedback capacitor has a significant impact on sound quality. This model specifically uses the Japanese ELNA Brown God series capacitor.
Customers can choose to purchase finished boards or kits. Finished boards that have been tested and ready for use come with a six-month warranty. The kit needs to be self welded.
