Hi leo Thanks once again for guiding me through repair process. Regarding the voltage issue you are right that my power supply has poor regulation. As you suggested I will try my best to replace those

They are more likely to explode when fed 230 V ~, and that is often what comes with 50 Hz (I know, not in east Japan, Jamaica, Cura?ao, Bonaire, Barbados, and a few parts of other countries). If they

Hello Saroj, this is a good start! You confirmed your scope has the typical issue, it's almost always the primary power supply with problems. The Power Supply are basically TWO switching inverters

Hi Tom, Sorry, yes you're correct, that'll teach me for posting late at night! Unfortunately, I don't have access to an ESR meter, however the need for one arises often these days so perhaps it's time

That spider is definitely screwed :-) Rick

Hi Max, I guess you mean A10, the main board. At least on my schematic. Anyway, do you have access to an ESR meter? That would be a little easier than a shotgun approach. But here are the caps to look

REALLY??? You should know better! The next time, before you ask 8,000 members from TekScopes for the answer to this trivial question, first try going to google. Type one word in the search field

Hi Leo I made myself a old style transformer type power supply to connect to the inverter section. Here are my findings. 1. Un loaded external power supply out put voltage---44v 2. Loaded external
