Rectifier vacuum tube: 5z3pX1 (SHUGUANG) replacement vacuum tube: 5u4c 5z2p 5z4pa 5u3c 5z3pa Pre amplifier vacuum tube: 6h9cX2 (Soviet Union) other replacement vacuum tube 6n9p 6sl7 5691 etc.
Power amplifier vacuum tube: 5881AX2 (SHUGUANG) other replacement power 6p3p el34 6p6p 6V6 kt66Machine technical features:
With power switch, triode 6w and super linear 7w output power, switch freely according to the speaker, the effect is different. (By default, the two small switches are dialed backward together, which is a triode connection method of 6w, and both are dialed forward, which is a super-linear connection method of 7w output power)Gold-plated RC terminals, pure copper crystal terminals, 0-4-8 ohms. Three-pin socket with fuse, 2 fuses

Power amplifier vacuum tube: 5881AX2 (SHUGUANG) other substitutions 6p3p el34 6p6p 6V6 kt66, etc.Bundle 3: 5881A stainless steel watch head, 96x60 transformer 86x40 outputMachine technical features:
With power switch, 5881A tube amplifier triode 6w and super linear 7w output power, switch freely according to the speaker, the effect is different. (By default, the two small switches are pulled back together, which is the triode connection method of 6w, and both are moved forward, which is the super-linear connection method of 7w output power) Plug different vacuum tubes, the output power of the machine is different, plug el34 is 8 watts plug 6l6gc 6p3p It is 9 watts, plug 6v6 kt66 is 6 watts, plug 6p6p is 4 watts, the machine is designed with a self-bias circuit, and there is no need to adjust the negative pressure.Product parameters:
