Description

New HiFi 6H3 tube Preamplifier machine 6H3 tube Amplifier with Matisse Circuit (SPECIFICATIONS) 1 (sensitivity Input): 150mV 2 (output Voltage): 1.8V (THD<0.03% RMS) 3 (Ratio S/N): 94DB 4 (Response Frequency): 10Hz-50KHz (-0.5DB) 5 (Impedance Input): 250Kohm 6 (Impedance Output): 600ohm 7 (Input AC): 220V/110V 8 (Consumption Power): 15W 9 (Dimension): 260*130*110 (mm) (W-D-H) 10 (Weight Net): 2.5KG 1. PCB is changed to blue military board, the working performance is more stable, the left and right channel layout is completely symmetrical, coordination, re-single point grounding wiring is more reasonable, and the background is quieter. 2. Resistors: All resistors use DALE resistors, and the power supply uses 3W American DALE capacitors: the signal part uses four-lead 99.99% high-purity oxygen-free copper US ERSE gold audio dedicated coupling capacitors, decoupling with fever German Redway Horse (WIMA). 3, the potentiometer is upgraded to the Japanese original type 16 ALPS potentiometer, the balance is better, the volume adjustment is more balanced and durable. 4, two 220U/450V Japanese black diamond capacitors are used on the power supply filter circuit, and the electronic voltage regulator filter circuit is newly added. The power supply continuous current operation is more stable, the anti-interference is stronger, and it is fully qualified for the large dynamic working state. , never soft feet. 5, the base: the use of a highly moisture-proof gold-plated ceramic tube holder. The tube is upgraded to 6H3, and the tone is sweeter and more mellow. 6 signal input is increased to two inputs, with a stable fully sealed switch to facilitate a variety of signal inputs.
