Replacement tube: 5z4p 5z2p 5z4pa 5u3c 5z3pa 5u4g 5z3p 274b, etc.   Pre-stage tube: 6h9cx2 (Soviet Union) other replacement tubes 6n9p 6sl7 5691, etc.   Subsequent tube: 5881Ax2 (Dawn) other replacement tubes kt66 6p3p el34 6p6p 6V6 6l6gc, etc.

Machine technical characteristics:   With power switch, the output power of triode 6w and super linear 7w can be switched at will according to the speaker, the effect is different. (By default, the two small switches are dialed back together, the triode connection is 6w, and both are dialed forward, which is the super linear connection of 7w output power)   The machine comes with a bottom plate by default, and it is made with our store's chassis. Only the chassis' reference chassis link, please click the font below (iron header chassis) to enter:     Iron case   The pictures are as follows:

The machine is made by scaffolding. If you need to know, contact the owner to send the internal pictures of the machine.

Gold-plated rc terminal, pure copper crystal terminal, 0-4-8 ohm. Three-core socket with insurance, 2 fuses, one spare. Three plug-in national standard power cords are provided.   1: The tube amplifier can only be (push) connected to passive speakers, and a pair of (2) speakers is needed. Cannot connect to the subwoofer and cannot connect to active speakers (that is, the speakers have their own amplifiers, and speakers with volume knobs cannot be connected).   2: The amplifier must be connected to the speaker before it can be turned on for testing. The rear stage of the amplifier cannot be unloaded. If the speaker is not connected, it will be unloaded, causing the primary voltage of the output transformer to rise, burning the output transformer or tube. 3: Plug in the socket or outlet of the amplifier for electricity, and cannot be shared with a computer or electric fan One, this will produce electromagnetic interference, causing the machine to communicate with the bottom noise. It is best to use a socket alone. The inside of the machine has been grounded, with a standard 3-hole fuse holder and internal spare fuse.
