RE: Asteroids horizontal collapse after 20 mins or so

Is there a point where its more dangerous to replace parts than to leave them be?

I have o-scopes, meters, and otherwise. I haven't used an o-scope in decades, but I don't think it would be too tough to renew any simple knowledge I might have once had. I can read a schematic, but I'm not a designer or even a technician, just a hobbyist.
