[The input voltage of the finished product can be changed to 110V/115V/117V and other values, which is convenient for customers in Taiwan or overseas. Please leave a message stating the required voltage when you take the photo. The voltage change machine needs to be shipped within 3-4 days after the photo is taken, and an additional $3 to change the voltage fee is required. Because the cost of a single customized transformer is higher than that of a batch. 】Note: When testing the machine, the horn must be connected. No-load test will easily burn the transformer or the tube (the tube will appear red)
.
6p1 is a commonly used power output tube in the previous tube radios, with a soft and mellow tone! Savor carefully, nostalgic thoughts emerge spontaneously! Especially suitable to appreciate you who are dominated by human voices!
[Schematic diagram, no 6E2 cat eye indicator]
The first two are 6E2 cat's eye level indicator tubes, which emit a faint green light after turning on, and jump up and down with the music, very interesting and beautiful!
To all buyers: The machines sold in this shop are all authentic pure tube amplifiers, and the output transformer is used between the tube and the speaker. Experts know that the role of the output transformer is indispensable for the guts of the tube amplifier! It's definitely not a machine with a front gall bladder and a back stone, or even a fake tube, which is just a decoration. It can be compared! ! !
Tips for choosing amplifiers:
1. Look at the number of transformers installed on the machine: authentic tube amplifiers need three transformers (the large one is the power transformer, and the two small ones are the output transformers). The font-shaped layout can reduce the interference between the transformers and ensure the The machine has a high signal-to-noise ratio! ) The power transformer of our product has a power of 75W, no heat or vibration, horizontal installation, without a cow cover, it is like a work of art. The output transformer is wound by the winding method of 3 clips 2 and the iron core is made of a new Japanese Kawasaki 0.35MM thick Z11 silicon steel sheet. The magnetic permeability of the Z11 chip will be higher, and the low frequency will be lower. The effect is much better than the domestic H14 and H18 silicon steel sheets.
2. See if the seller provides pictures of the inside of the machine: the following are real pictures of the inside of the machine.
Handmade diy, red walnut log case, the wood is dried and will not crack, after repeated polishing and waxing, the texture is rich, simple and beautiful! In the world! The upper top plate is made of 1.5mm thick iron plate and the lower bottom plate is 1mm thick aluminum plate. The advantage of using a metal top and bottom plate is that it can isolate some clutter interference!
The use of components is as follows:
RF107 fast diode full-wave rectification*2
330U/400V Japanese brand electrolytic filter*1
220U/400V Japanese brand electrolytic capacitor secondary filter *1
22UF 400V Taiwan electrolytic third filter *2
Hong Kong TE MKP 0.22UF copper foot film inter-stage coupling capacitor*2
Metal film precision copper foot resistor
Silver-plated ceramic socket
Japan ALPS 16 volume potentiometer
Copper gold-plated RCA socket and speaker terminal
Copper pin terminal
The 6p1 output cow and the power cow (No. 764503) are made by our shop and the quality is stable and reliable! All are wound with pure copper wire. The power cow works only at low temperature for a long time, and the output cow (No. 573001) 57*30 Z11 iron core, made by 3 clips 2 craftsmanship, wide frequency response.
The rated output power of this machine: 3.5w+3.5w (due to the advantages of strong overload capacity of the tube, the actual undistorted output power is equivalent to 20w+20w transistor amplifier!)
This machine has two impedance output modes, 4Ω or 8Ω. This machine is suitable for selecting high-sensitivity small bookshelf speakers, full-range speaker speakers are of course better! Since the tubes of all levels are working in Class A amplification, the distortion is small, the tone is sweet and soft, and the sound resistance is extremely high!
For safe mailing, our shop uses thick packaging, and the electronic tube is also individually packaged. You can plug it in after you arrive!
