etpm@whidbey.com: Aug 21 09:35AM -0700 Greetings Jeff, I grew up in Cupertino and Saratoga. I spent most of my summers when I was a teen in the Santa Cruz Mountains. We used to hitch hike from Saratoga to Los Gatos and then to Santa Cruz to enjoy the beaches. Camped in all sorts of places in the Santa Cruz Mountains that were not actually campgrounds, but just places where we wouldn't get caught. Also Big Basin and Henry Cowell state parks. Now there are all these fires in your area. It's making me heartsick. I hope you are OK.

Modern film caps are massively better & smaller.     NT

However, why do you suppose it is that motor run caps are so big for their voltage and capacitance ratings compared to other non-polarized caps? I'm serious.

vjp2.at@at.BioStrategist.dot.dot.com: Aug 21 03:36PM Thanks. Yes, I haven't done much soldering in a few decades. It is on the board and seems rather tiny and fragile. I tried to straighten it out with tweezers and it seems to have broken or at least gotten pushed in. Certainly the 2011 device is fully depreciated and its economic life has expired, but I'm comfy with it. I guess opening it and trying once can't hurt if it's already gone. Although my repairs usually require opening it, giving up then a while later getting some inspiration to try again.     -- Vasos Panagiotopoulos, Columbia'81+, Reagan, Mozart, Pindus blog: panix.com/~vjp2/ruminatn.htm - = - web: panix.com/~vjp2/vasos.htm facebook.com/vasjpan2 - linkedin.com/in/vasjpan02 - biostrategist.com ---{Nothing herein constitutes advice.

Standby...     That's what they are. The fuse element is coated with a chemical that burns as soon as it reaches its critical temperature to ensure that it opens quickly. They were use in the cathodes of Horizontal output tubes, and some solid state circuits. They are very fast opening fuses, and similar to the 7200V fuses used by utilities, except they use gunpowder to quench the plasma. Both methods can run right below their critical temperature without opening. Once any part of the element reaches critical temperature, it opens. No sagging fuse elements that change their fusing current from running too hot without opening. I've seen some AGC fuses where it had melted, and drooped to the glass without opening.   -- Never piss off an Engineer!   They don't get mad.   They don't get even.   They go for over unity! ;-)
