Generally speaking..an output failure is more caused by accidentally DC income..like put the signal output in a 15V supply...or else worst. That mean .....check the driver transistor and associated di

Hi Jerry here my two cent based in my own experience. If the goal is obtain a perfect circle hole in a aluminum panel ..then use a piece of jean fabric...put above the panel covering the hole zone, an

Here my two cents.. Better buy a mainframe TM501..or better yet ..TM503 is fine since without cover you can work in the circuits and fix and tune it....not so easy with TM501. Right now on Ebay you ha

Hi Magnus..the facts is that as we all know , the capacitor act like a rectifier, but no clue why..unless aluminium oxide work like cooper oxide rectifier..?.At this time I never read such property on

Hi bruce..your coment and the pdf about capacitor make me to rethink about why the aluminium oxide can work as "rectifier" dielectric. Since aluminium oxide is a very stable dielectric and time is req
