Sansui G2000 with right channel distortion and phono/stereo-mono board issues?

This Sansui is not the most powerful as far as watts but does have a real clear sound to it, it's easy and pleasant to work on. Had distortion on one channel and in phono, the mono stereo switch one channel cute out on stereo...but parts are still available and was able to fix it... thanks for watching and am looking for comments on this amp, especially on the resistors R72-73-74...
