Re: Input RF switch fault found on TinySA ultra


 

Well, since over 10 years I'm very happy with my headband magnifier. Those days bought from RS. Article Nr. 606-989 looks approximately the same. It fits also over a pair of glasses. But (yet) I don't know what about the magnification. I'd have to check it in my lab. But approx. 2.7x - like that model offers, could well apply. I only don't remind that it was that expensive.?
RS offers also a more affordable product that's available up to 3.5x (Shesto, not a RS PRO product)
Its advantage above a microscope: better feeling of hands movements (and greatier viewing angle), in a word: less indirect handling experience.

However, sometimes I need to check solder efforts using a small eye magnifier x5 or x7, I mean the sort that is in a conical formed tube such that you can hold it by your eye surrounding. Not because I do so (often it simply falls down), but simply by helding it by fingers while looking at approx. 10-15 cm distance. The tubing helps reduce reflections from room light. Sometimes I uses this lens when I only have to use only one hand to re-heat a questionable joint with the solder tool (evtl. prepared with a bit application of Rosin paste.

Yes, you definitely need a microscope.
