.......
4. If you have more than about 0,2 V the cap needs to be replaced and this could be a cause for your jitter

Are you sure? LOL, then my caps are really crap!!  :roll: :roll: They don't show an AC ripple, but AC waves!  ;D Or there is something wrong with my test setup (I measured the values also with another multimeter, same results). Anyway, pictures say more then words:

1. The real big fat blue one, top right:



2. The blue one on the left:



The grey one on the bottom:



So, replacement is in order? Unfortunatley I couldn't find what the capacity/voltage of these are. Does someone know? Or is there anyone with a Qix who can measure theirs, I can't believe that mine are that way off!

Side question, how are the little grey 'caps' on the next picture called and what do they do?

Yep transistors those are :)

Those values are impossible. I guess your meter is confused.....you need a better one :)

Looks like your meter is autosensing, so its actually measuring DC now..

do you have a manual of that meter, perhaps there is a way to force measuring AC.

Both my meters give the same result.

Thanks,  I thought that transistors were far more flat,  smaller and mostly black. These must be old type of models.

There are many different packages for transistors

I have this one, very pleased with it, and it has separate DC and DC so not auto sensing.

I know its not a fluke, but it never has let me down, and the price for this 2e hand is very reasonable, i know that i payed alot more Retail..

EDIT, i looked wrong, i have the Metex M3800, but it looks almost the same, so i guess the features are also the same
