KITS No 5 electron tubes

Board needs its own welding, welding may be able to test, plus $ 12

 2.0 thick copper double Shen Jin

Kits architecture 6SN7 + 300B single-ended output form

300B previously been a lot of people like to do with scaffolding way, big project, wiring too, reliability and performance are affected, the appearance does not look good, there are well-made PCB production, we can completely resolve these difficulties. Because the element is not much free testing, and manufacturing a difficulty almost the same LM1875

1.6SN7 + 300B single-ended output in the form of design, the most authentic classic 300B program.

2.2.0mm after quality Immersion gold / pewter blue printed circuit board (203 * 107.2mm), copper thickness of the double copper

3. The signal to noise ratio is extremely high, quiet background

4. The circuit is free debugging, making simple.

5 sophisticated materials, all of the new member, the coupling capacitor using the best French vocal SCR Suren capacitance, 300B tube holder 95 also preferably just fine ceramics special 24K gold, pledged to play a perfect circuit, detailed material list, see bottom of the page, this configuration is better than a lot of expensive finished machine.

The board has a good standard of each terminal voltage parameters, transformer condemnation can, two points marked L is connected to the choke (each 50 yuan)

Commonsense Note:

1. The output transformer can not take the speaker on the boot, load will burn.

2. The input voltage to the terminals should strictly follow indicates that the connection can not be wrong.

3. Do not be hot to heat the tube. After power was installed properly no abnormal tube
