So I have a macintosh plus 1mb 120vac from 1987 and I have had some problems. so I picked this mac up at savers for $2 back in December and it looked like someone had it in a garage and also had put some bottle with some fluid on it that had leaked into it but had dried. When I turned it on it constantly made the start up sound and would some times respond with the floppy drives, no picture on the screen. The reasons I did not clean it first was to test the before and after affects so that I didn't damage anything in the process, and the other reason was I'm 16 and my dad wanted to only give it to me for Christmas. So a week or 2 later I opened it to see some corrosion but every thing else looked fine. after cleaning the board it would click slowly. So I don't know if it was a good thing or not but I started replacing the caps. I replaced all the caps I could and checked the ones I could not replace with a capacitor reader. After checking every other diode and transistor I switched it on and it started clicking really fast. I suspect that its a flyback after bringing it into my electronics shop, because I go to a vocational school. I don't have $100 right now to buy a replacement, I would buy a analog board online and steal the flyback, but still its a little over pricey. I mean $40 bucks is a lot, is there any other alternative part or anyone that has another idea for the problem. I would love to have this thing working because I have always wanted one since reference of them through shows and the popularity of them. This would not be the first one I have looked at, I'm not a noob I have worked on one in the past that also had a dead flyback because it was left in a cemetery and the screen was smashed in. It has a mother board that's in better condition but its my friends and the mother board is not the problem. I'm at a dead end what do you guys think I should do. https://www.youtube.com/watch?v=2aERGBzecyE here is a video of the sound
