Hi everyone. I'm building a 6P14 / EL84 push pull chinese kit (6P14/EL84 Vacuum Tube Power Amplifier Class AB Stereo Audio Amp DIY KIT 13W+13W 940106145338 | eBay) . XraytonyB did a an excellent build series of it on youtube. It seems like a good kit but the instructions are absolute crap. I'm to the point of wiring the transformers. The kit included a thick shielded wire, about the size and shape of a computer power cord. It consists of 4 small wires (appx 22-24 gauge each) color coded red black green and yellow, encased in a thick black rubbery cord. No end terminals on either side. The instruction don't make mention of the shielded wire and they enclosed multitudes of miscellaneous wires. I didn't use any of them as I wanted to use a higher quality wire. I'm a novice and I don't know the rules of thumb regard where to use the shielded wire. I can only guess perhaps it should run between the 110v a/c input to the power transformer? If anyone can enlighten me I'd really appreciate it .
