You will find description of possible configurations here: AudioSector-chip amp kits, dacs, chassis
Amp and PS as per attached schematics. The yellow foils strip inside schematic sheet supplied with a kit is for chip isolation from a heatsink. For more general info on amp building please refer to this thread: Commercial Gainclone kit- building instructions (Please note that the diodes on LM4780 PS board are installed opposite to LM3875; just observe white stripes marking metal tabs orientation). If you need more specific info, please post questions here.

I have soldered these into place but still not sure if its right...
I'm gonna join the bridges between boards coz I can do that bit.. I'm still not sure about other resistors ID yet. All the pics I can find look like different parts in places to what I have. Chill for a bit, try again soon. |

This is how the resistors should be installed for parallel configuration. Please note that R0 is intentionally omitted. Also ad the jumper and Rm as pictured here: http://www.diyaudio.com/forums/attac...lel-bottom.jpg

Sweet.. just gotta put the large ones in now.
I will put a picture up when I've got them done... This is my first ever time soldering a pcb so its taking me a little longer than most. |

MUR's??? The ones I see are the same way I've put mine in, but I notice that on other pics the flat metal side is towards white line, mine are opposite way. Have I looked at wrong kit and got it back to front?

So to be clear, the diodes in LM4780 kit install as pictured:
