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.

I was able to remove most of it with rubbing alcohol and elbow grease.
EICO 950B – Repair/Restoration
To find out more, including how to control cookies, see here: Remember rules for series capacitors. I believe it is a Hay bridge. This instrument always finds a way to give you a healthy shock sooner or later. If the eye tube gives a full degree shadow with clean, sharp edges with the pointer within a few percent of the correct values, the bridge capacitors are okay and nothing will eic gained by changing them.
Dec Mon 31, 7: Repairs should only be attempted by a qualified technician. Elco, in the process of looking for something, you come across a few folks, who possessed a wide spectrum of skills and abilities.

As the tube heats up slowly, it should not cause any trouble euco 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. We do not provide free personalized troubleshooting. Just out of curiosity, I’d like to know when Eico finally discontinued this model.
Perhaps it was made up to time the eido out. Do not run down the voltage fast after leak test on a high value cap. Oftentimes otherwise nice examples have a “crunchy” voltage pot, that’s why, and I bet replacements are tough to find? The only draw back is that the unit doesn’t have a volt meter so you should check the voltage control using a vom as I first did to see if the marks on the voltage scale are close.
Receiving an electrical shock is not fun and I always take steps to avoid it. I wish I had come across this valuable article before.
Extreme caution must be followed with any vintage capacitor tester because very high voltages are present during repair and while operating.
While I wait for my precision caps to arrive, I can finish rest of the tasks, replace the last few 0. Yes, the knob is wrong.

You may also like. More models will be added on an ongoing basis as I find the time. When the bridge is far from balanced, the target area of the magic eye tube glows completely closed green, and in fact overlaps. This isn’t done on the leakage test, I get that, but when measuring capacitance. eicoo
Email required Address never made public. Otherwise, it’s in great cosmetic shape. One of the best, eido most often overlooked features of a bridge-type capacitor tester like this is the power factor measurement for electrolytics.

Nice to see a great equipment being put back to use again. This unit you simply increase the voltage a little 950g a a time while watching the eye tube to show the capacitor under test is taking the charge.
Users browsing this forum: The values can be hard to source. Can someone explain how the power factor test on this model works?
I ieco ready to head back to my TEK Project. You could google it to find more details. Mine tops out at VDC.
If you have some new caps on hand that are slightly lower eeico value than what is needed, you can select caps to add up to the necessary values. In any case, if you do not find the exact value, try a combination of parallel or series caps, e. If I can find it, I’ll eventually swap them around. I contacted the seller and he was a TV repairman from Massachusetts.
The EICO B, the resistance capacitance bridge and the capacitor leak tester — I do have other tiny things that can measure capacitance, but nothing compares to this one, or the Heathkit or a high voltage DC capacitor leak tester.
This item doesn’t belong on this page. I also still need to clean off the remains of the protective film over the front panel. They should only be used by knowledgeable technicians. You get the entire set of 3 reference caps 1 of pf, 1 of 0.
I replaced 3 capacitors 2 didn’t look good and one was wrong value. Overall a great piece of hardware!
Cosmetically, it still had it’s protective film over the front panel that was never removed. You just need to keep the ration capacitance ratio the same. Books Support This Site:
