Restoring a Predicta Tandem
#16

I was doing some more testing last night, to tr and find what else is going on. I ran into a little issue, I'm hoping Bob may know the answer considering all the boards he's rebuilt. I have what looks like original resistors on my board but they are different values from what the Photofact says. R67 and R57 they both test good according to the color codes. But they dont match the list. for R67 I have 1.9m and R67 I have 470k. Also according to the Photofact in the bottom of the unit I am supposed to have 2 capacitors that arent there, I dont even see a trace of them, they are C5 and C54. Is it possible I have a later chassis or a later Photofact? What do you guys think?

So far I found that C22 is open, R43 is open, C43 tests higher than its supposed to be at 1.2, R62 is open, C42 is open, R50 only meters out to about 46.5k and has been replaced at least once. Hopefully these are whats causing all my problems. Are they inline with my problems?
