Hi,
This looks like a nice "father and son" project. What power input voltages can it be used with?
Best regards!

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, Jeffrey
Looking Good, I'm contemplating on purchasing one of these kits. What speakers and efficiency are they that your using.
Does the 220v power supply run hot at all with the 240v mains power you have there.
Cheers

Congratulations Jeffrey! you really did a great job for a newbie. Thanks for sending me a lot of photos of the assembly process. I use some of them in the assebmly instructions.
Hi, Whiting
My speaker is fostex 125 full range, sounds pretty good. 220V version works perfect for me, transformer is warm but not very hot. Slight high temperature has benefit for the performance.

Hi Jeffrey,
Is that a volume control on the front of the amplifier? how are the instructions for this kit? Are the instructions and diagram on this thread all that is included with this amp? I've never done a project like this before. I would definitely need a little more detail.

Hi bbowes,
Sorry that we are lack of instruction for these kits. It's not an easy work for us to write an manual in English. In my own opinion, a manual can only tell you how to wiring it, but can't tell you how to make it sounds good. It's depends largly on experiences with grounding, shielding and so on. Anyway you are encouged to begin with 6P3P SE, it's not too difficult for beginners. Many customers get the instructing throug email or even online chatting. We are happy to help you in building your first amp.

Ray, if you took a detailed photo, or two, of the underside of the project, and posted for us, do-it-yourselfers would have something more to go with. That would go a long way toward making a successful 'build'. In turn, you would sell more products, with more happy builders.
As the saying goes, a picture is worth a thousand words.

Hi John
Thanks for your good suggestion. We do have some photos of the inside, but it's largely depend on the builder, no "standard" soldering. I will study some cases and post inside of some well built amp soon.

Ok, you have me sold on this one as a good starter for me. I think this is the one I want.
I have a question. Do you have any of those nice little transformer covers, like the FU-10, that are good fits for this amplifier? If you do, I will be glad to pay you for them along with the kit.
I'll wait on you to get back to me.
Thanks for your patience Ray.
