Hi folks!
As I told you, I've changed cooler and backup batery. These days, I just ordered some cap and my plan was to change as many cap in scope.
For now, I did only for source.
I've attached here a list and now I want just to make some correction: there are 2 cap which in tek scheme are 180 micro/40V and I've changed with 330 micro/50V.
Surprise..
on the screen I get some "dots" arranged in place in which there are trace and readout characters..
it took some times until I catch about this. I think that anyway, if there are in a filter (low pass) it's ok. But charge it counts and 330 micro was too much.
So, I put back 180 micro and all ok
with this occasion, I will put for all rest the value in Tek scheme (even with some increase of voltage - not more than 30-50%) and temp at 105 Celsius.
So, the correction it's to say that if somebody want to re-cap source, better to keep same values like Tek in scheme.
below, there are values which are correct:
C1016 .068 µF 275 Kemet X2 SuppFilm
C1018 .068 µF 275 Kemet X2 SuppFilm
C1021 290 µF 250 Nichicon PW
C1022 290 µF 250 Nichicon PW
C1110 250 µF 35 Panasonic EB
C1111 250 µF 35 Panasonic EB
C1113 180 µF 50 Panasonic EB
C1114 250 µF 35 Panasonic EB
C1132 250 µF 35 Panasonic EB
C1116 180 µF 50 Panasonic EB
On the other hand, that "issue" for which I've open this post remain... I'm not sure if Tek make a project in which when turning the SEC/DIV knob clockwise, then shifts the trace to the right, and vice-versa....
maybe somebody knows if it's normal.. (Many thanks Jim - exactly same issue I have, I can live with it but maybe it's a way to fix it..)
