Hey everyone! So I've had a Marantz 2270 on my bench over the course of the past few weeks. I've recapped all of the boards aside from the AM and FM boards (everything was working okay following the recap), and I replaced a bad transistor as well. After adjusting voltage, DC offset, and idle current, I went to test it out with audio. My result was not good as I turned up the volume (a spark and smoke somewhere around the halfway point). Now my speaker relay won't click in any longer. Not sure where to go from here. Transistors seem to still be good, so I'm not sure where the problem would be. Any direction would be greatly appreciated!
