Nice try. The stuff I fix is not my own, it is incoming with unknown history. Once I fix things they generally stay fixed. Think of my testing as a form of HASS... I don't like to get things back which I repaired. If capacitors are weak, I would rather replace them than play with reforming.

I've seen a strong relationship between the wasted time spent fixing extra things that where fried unnecessary, with how careful one is at initial turn on. Monitoring the wattage, using a Kill-A-Watt meter when turning on Old things can save 'futzing time' in the long run. And the most time saving thing I've found besides "apply power and throw it out if there is smoke or nothing", is to do a complete visual inspection inside, to insure things are still the way they where designed to be, BEFORE applying any power. Yes Variac, My spell checker thanks you for teaching it the correct spelling. I find it one of the more useful pieces of test equipipment when checking/modifying things to get max Nut-Precision from them. If changing the line voltage or the temperature a little causes ANY measurable effect on performance, then for me, it's time to change something and made it better, which can often be done with just simple changes (and a lot of futzing time). ws ************ Peter Gottlieb nerd at verizon.net Hmmm. 99% of the time I just plug things in and see what happens. That's what they were designed to do. If something pops I fix it from there. If a fuse keeps blowing I use the light bulb in series trick. On older tube gear I do "softly" bring it up with the variable autotransformer (Variac, Powerstat), but that's only really because of the capacitors. Just my 2 cents. I do fix a lot of stuff, though, and don't like to waste time futzing when I don't have to. Weak parts get replaced. If they were likely to fail enough to do so when I just plug something in, they need replacing anyway. ****************** On 10/11/2011 1:14 AM, David J Taylor wrote: >> The proper use of the variact's output voltage has a learning curve, >> because >> equipment with switchers behave differently than things with linearly >> supplies >> >> ws > > Warren, > > It's likely "Variac" you mean, not "variact" > [1]http://en.wikipedia.org/wiki/Variac#Variable_autotransformers > > Cheers, > David _______________________________________________ time-nuts mailing list -- [2]time-nuts@febo.com To unsubscribe, go to [3]https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
