I have been using the BK Precision 879B: http://www.testequipmentdepot.com/bk-precision/lcr/879b.htm?ref=gbase&g… CKj82-uIoMgCFRNrfgodYOYOvA It's at a completely different price point ($250-ish), and much more than an ESR meter - but it's a bargain for a full R,C,L,Z meter. Very useful to know not only the ESR, but the actual value of the capacitance (which for big power supply caps could have diminished significantly over the years). It can measure components at 100Hz, 1000Hz and 10Khz. You could not justify it for a single power supply repair, but if you do a lot of old electronics restoration projects, it is a precious tool to have. I couldn't live without it now. You can see it in action in the middle of this video here, in this case exonerating a capacitor that I sure thought was the cause of my power problem, but turned out to be perfectly good: https://www.youtube.com/watch?v=lqD6xVI6qNs Marc ====================== From: Ken Seefried <seefriek at gmail.com> Subject: ESR Meter Recommendations I'm going to be working on my 11/730s power supply, so I'm in the market for an ESR meter. I've seen some (older) recommendations for the AnaTek 'Blue' and various 'Dick Smith' derivatives. However, eBay is flooded with knockoff Mega328 based ESR/Transistor/SCR/etc. testers all looking like: http://www.amazon.com/DROK-Multifunction-Mega328-Transistor-Capacitor/dp/B00 NKY3M1W/ref=sr_1_16?ie=UTF8&qid=1443561246&sr=8-16&keywords=esr+meter Anyone had any experience with one of these devices?
