Do you need to check ESR on electrolytics or just for leaky old paper caps ? I've heard the Sprague Tel-Ohmike's are pretty nice, but the newer models can be pricey. Personally, I use a vintage Solar CB-1-60 and Simpson 383A Capacohmeter. Both work well for testing micas and paper caps but are somewhat limited for electrolytics. http://farm7.staticflickr.com/6175/6198858323_73f82d2c8a.jpg (http://www.flickr.com/photos/70039806@N00/6198858323/) http://farm6.staticflickr.com/5011/5541759813_9f89fe699a.jpg (http://www.flickr.com/photos/70039806@N00/5541759813/) bob91343 04-06-2012, 09:21 PM Oh my goodness, that Solar unit is the same as one I used to have! Such memories it evokes! With a 6E5 electron ray indicator and a 1-v rectifier, I got years of use out of it. Right now I have two instruments, both General Radio bridges, that measure capacitance at low frequencies. One also measures ESR. If I need a high frequency measurement I cobble up a circuit with an RF generator and an oscilloscope. I had a Hickok VTVM with a capacitance function but that didn't actually measure capacitance; it measured voltage drop at 60 Hz, which is only valid for low loss capacitors. chipper 04-07-2012, 06:44 PM Yes; That test eqoupment looks great, I would like to find something that could test just about any type found in vintage tv and radio set's .
