I've never built one of these kits (yet) but the safety ground and the signal ground(the one off of the main PCB) and a chassis ground should all connect together with individual wires at the negative side of the last capacitor on the power supply PCB. This is called a star ground. If they are not recommending that you use this configuration in the instructions then shame on them. This is the best way to ground any audio circuit SS or tube. It almost gaurantees that you will not get a ground loop induced hum coming out of your speakers. Also remember to twist the leads on the primary of the power transformer together when routing them for wiring and the same goes for the secondary leads as well as the primary and secondary leads for the output transformers. I hope this helps.
Take a look at how the wiring looks in this amp:http://www.idealinnovations.ca/gallery/s30internal.jpg
