I took a chance!
Well, I replaced R48, R68 with new ones. Replaced two O/P transistors, resoldered all them other transistors I removed, plus associated wiring. And took a chance! I turned her on, ON LED flashes, then stays on. All other LED's are functioning as well. Then the speaker relay engages... OH MY GOD! She has stayed on and the fuse holds. No smells or anything out of the ordinary... Yet! I'm gonna let her warm up for 20 minutes and check DC offset. Now I know taking chances isn't always the best idea, but hey, somebody has to!
