Path: /eico/b/. This is the BAMA archive. These manuals are available for download and free of charge. I am now accepting new manuals for inclusion in this. DESCRIPTION. Your new EICO Model Resistance-Capacitance-. Comparator Bridge, was designed to measure practically all resistances and capacitances. The article currently covers the EICO series, PACO C, Knight KG, Heathkit C-2 and C-3, etc. (More models will be added on an ongoing basis as I.

Leave a Reply Cancel reply Enter your comment here PF was added to these testers years ago before high efficiency electrolytics came around. Fill in your details below or click an icon to log in: Unless your photo is wrong, the model had a plastic pointer that reached all the way to the outer scale.
PF was added to these testers years ago before high efficiency electrolytics came around, and servicemen noticed bad filters tended to get hot. For those caps, I’ll use the closest tolerance parts I can get as long as the price is reasonable. You may also like. Jun Mon 17, 3: I replaced 3 capacitors 2 didn’t look good and one was wrong value.
Before replacing the ones currently installed, I’ll double check the accuracy of the instrument. Extreme caution must be followed with any vintage capacitor tester because very high voltages are present during repair and while operating.
Jun Sat 22, 7: Sometimes, in the process of looking for something, you come across a few folks, who possessed a wide spectrum of skills and abilities. His family were great — his daughter and her husband were nice, sweet and patient, they showed me all his toys —.
Previous topic Next topic. For Leak testing pot P3 controls the output voltage. What it means, what to look for, etc. Skip to main content. When the bridge is far from balanced, the target area of the magic eye tube glows completely closed green, and in fact overlaps. The unit worked when I got it and the changes I made were for safety reasons.
This instrument always finds a way to give you a 950h shock sooner or later. I checked the transformer as well in this process and saw the heater glow eicl both the tube and the magic eye. Show More Show Less.
His family were great — his daughter and her husband were nice, sweet and patient, they showed me all his toys — Robert Merville Gale — I would like to dedicate this project in memory of this wonderful and brilliant soul. You can use the checker to test its own capacitors by connecting some brand-new plastic film capacitors that are approximately mid-scale on each range except eicoo “D” range, for which you’ll have to use a new electrolytic to the test terminals.
This isn’t done 9500b the leakage test, I get that, but when measuring capacitance. Do not run down the voltage fast after leak test on a high value cap. I had a hard time getting those film caps but managed to get them finally. I’m having the problems you described on the highest ranges; so, I think I need to track down new capacitors.
Vintage EICO Resistance Capacitance Comparator Bridge Model 950B
Mine developed an internal short in the value potentiometer and took out a winding of the transformer. And here you go, this is what it looked like on the inside. Nice to see a great equipment being put back to use again. In any case, if you do not find the exact value, try a combination eioc parallel or series caps, e.
It worked when I got it; but, I decided that it needed to be overhauled to insure that it continued to work well. Yes, the knob is wrong. You get the entire set of 3 reference caps 1 of pf, 1 of 0.
EICO B – Repair/Restoration – Lazy Electrons
Remember rules for series capacitors. Another thing to note is a bridge is much more certain than a handheld digital capacitance meter for “mystery caps. During component value testing, the magic eye tube serves as the null-indicator.
You just need to keep the ration capacitance ratio the same.
Jun Tue 18, 5: As the tube heats up slowly, it should not cause any trouble even if I have a high value cap, but I wanted to play it safe and keep the surge current as low as possible to protect the rectifier tube.
Cosmetically, it still had it’s protective film over the front panel that was eifo removed.
