Schematic
Click the image to open in full size.

Assembly instruction:
1. Assemble valve socket, audio input socket, audio output socket, power socket and power switch.
2. Install power transformer and output transformer.
3. Check assorted resistor and capacitor .Test whether audio input socket, audio output socket, power socket, power switch, power transformer and output transformer are shorted with chassis.
4. Connect valve filament line of power transformer and output transformer with relevant sockets.
5. Install resistor and capacitor of power-amplifier after installation of resistor and capacitor of preamplifier.
6. After soldering, check whether each solder point and connection of circuit is the same with graphic expression in electrical schematic diagram.
7. Test whether the voltage of power output and valve filament is right. (It is normal that no-load voltage is higher.)
8. Plug in rectifying tube, and then check whether power is the same with graphic expression in electrical schematic diagram. (It is normal that no-load voltage is higher.)
9. Check whether complete machine connects with valve socket. (It is normal that no-load voltage is higher.)
10. Plug in power amplifier when voltage of valve filament is right. Check whether cathode voltage is the same with graphic expression in electrical schematic diagram.
11. Then plug in preamplifier valve, and test whether working point is familiar with graphic expression in electrical schematic diagram. If it is ok, signal can be inputted to test the sound.

Hi,

These amps seem pretty nice and easy to be made for a newbie like me.
I hope the package from you, quickly arrived.
I am curious about the sound when paired with my uFonken.

Thank you

Default Marks of transformer

The power transformer are marked with Chinese. Here's a picture that marked with color dot for the cables, for your reference.

Hello,
Are the 6P3P tubes equivalent to the 6L6's?

Yes it can be replaced with 6n3c, 6L6, 5881, KT66, EL34 without (or with minor) modifications The sound can be improved with EL34 and KT66 as my experience. Haven't tried other tubes yet. 6L6 should have the same sound quality with 6P3P.

Default Very important notice

I discussed with a Denmark customer all night long about his 6P3P kit. He finished soldering the kit but the speaker is crazy shouting. At first I told him to check all the connections, groundings and values of components. He worked for a few hours and sure that everything is OK, but the amp is still shouting.

Finally I realized that the problem may be caused by the feedback loop. Maybe he wiring the wrong polarize of the transformer. I asked him about the polarise of the output transformer, he seems to be very surprising: "Does that important?" OK, you can imagine what happens next. Now his amp is working perfect.

Well, the polarize of the output transformer does matter, or the negative feedback will become positive and the speaker will shouting.

There're marks on the transformer which marked with P, B, 0, 4Ω, 8Ω, and the color are red, blue, black, yellow, green. P must be connected to plate of 6P3P, B connected to power supply, 0 connected to ground, 8Ω to feedback resistors. Please take special care when you are building your amps.
