Description:

this is diy kit, you will receive a pack of components, and need to solder them together by yourself, the image is only for reference of how the board will be after soldered!!!

1. Using Beijing 6N3-J military grade tubes.

2. Main filter capacitor capacitance using imported Japanese 400V 100UF (Please note: Non figure 180UF), the output coupling capacitor with the top Dutch PHILIPS capacitance (capacitance may be due to shortages adoption of alternatives, the principle is the same level or advanced replace). Coupling capacitors using original French imported disassemble Tom patrol 0.47UF film capacitors.

3. Resistance selection Rings metal resistance, the main circuit employs a precision of ± 1% metal film resistors rings, ensure the machine a good signal to noise ratio. 

4.PCB using 1.6mm thick double-sided sheet, 2.0 oz copper thickness, HASL whole process to ensure that the size of the current through the good performance. PCB-class quality.

5. 9-pin ceramic tube silver-plated copper base, mounted blue LED lights. This product requires 10W enough power transformers, transformer output voltage: 150V 40MA; 6.3V 1A

6. The amplifier board layout is reasonable, beautiful, minimal current sound. 

7. The volume of the finished plate: plate plate length 12.5cm width 9cm height 7cm 

8. The board default setting is 7 times zoom!

Peak noise floor 8.8MV, a relatively low level! Plate default setting is 10 times magnification! You can adjust the resistance to ground the noise floor down to 5MV, zoom around in multiples of about 5 times.

Package including:

1x 6N3 Vacuum Tube PreAmplifier SRPP Board Fit for 5670  (not assembly, will receive a pack of components)
