Broken Binding Post on Yamaha Home Theater Amp

I am a new Audiogon member and have a broken off speaker output binding post on my Yamaha Avantage amp. I took the top off of the amp and saw that the binding post is connected to a circuit board via a pair of solid brass bars rather than the expected wires. I have some basic soldering skills, but this looks like special parts are going to be needed. Thoughts or advice on this? Thanks in advance.
