Kit DIY KSA5 Headphone Amplifier Headphone Amplifier/Preamp/Desktop Amplifier

Description: Kit DIY KSA5 Headphone Amplifier Headphone Amplifier/Preamp/Desktop Amplifier Note: The product is a loose set (you need to weld by the player) PCB size: 254mm*190mm*2mm Input voltage: recommended +/- DC21V The transformer power is recommended not to be less than 40VA. This version is designed by Kevin Gilmore, an international expert in the DIY industry, and is the closest to the quality of the original KSA5. After comparison and audition, the core version and castrated version of the instant TB are shown; This version is of very high quality and can be used as pre-amp, headphone amplifier, and small power amplifier. The configuration is as follows: 1. 35 Nijikon 1000UF capacitors, WIMA and silver mica electrodeless capacitors from Japan; 2. All small tubes are matched with PHI silver noodles on the same pole 3. The input tube is designed with golden seal 2N5564. This tube is of high quality and has the best sense of hearing. However, the pass rate of new TB tubes is less than 10%, and the price of second-hand tubes is extremely high. The default configuration here is Toshiba 2SK366. Very 1% accuracy matching, please pay attention to the foot position when installing, students without obsessive-compulsive disorder can make up the difference to buy a second-hand 2N5564 gold seal tube tested by the graphic instrument; 4. Existing a small amount of PHI resistor package, after using up, the whole line will be changed to 718 factory resistor package. Note: The power resistor is still produced in Taiwan. 5. In order to ensure the sound quality, please use the supporting KSA5 special power supply or HP-X or HP-1 power supply. Do not use Shenma LM317-337 and Watian power supply; 6. If your audio source (CD player, DAC, player, etc.) is less than 1000 oceans, please purchase carefully, there may be a bottleneck effect that cannot achieve the desired effect; 7. This version of debugging is quite simple, just adjust the quiescent current of the end tube to 80-120MA. package1*Kit DIY KSA5 Headphone Amplifier Headphone Amplifier/Preamp/Desktop Amplifier Payment Details We only accept Paypal Payment.
