This is how pristine it looked when I picked it up. Posted in Test Equipment on August 23rd, Most testers you dial up the test voltage, push the leakage button and wait for the eye tube to open which seems like forever. Jun Tue 18, 5: I have to disclose, I learned this from U-tube videos. Unless your photo is wrong, the model had a plastic pointer that reached all the way to the outer scale.
I replaced 3 capacitors 2 didn’t. It worked when I got it; but, I decided that it needed to be overhauled to insure that it continued to work well.
If the eye tube gives a eco 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 be gained by changing them.
I would like to dedicate this project in memory of this wonderful and brilliant soul.
But it does get quite warm if I run for long. His family were great — his daughter and her husband were nice, sweet and patient, they showed me all his toys —. Previous topic Next topic. Overall a great piece of hardware! Depending on where the controls are set, a healthy shock awaits if you touch either one and the case at the same time. I have put in a new power cord, a new y-capacitor and replaced all the electrolytic ones. Fill in your details below or click an icon to log in: PF was added to these testers years ago before high efficiency electrolytics came around.
The power cord was changed to 3rd pin and grounded earth to chassis. Here’s an example of a cap that is 0.

On the other end of the spectrum, I read on the Internet that someone purchased one of these new from Radio Shack in ’73; so, if that’s true, that means this tester eco in production for at least eicco to 20 years. Most relevant reviews See all 6 reviews. Remember rules for series capacitors. I also still need to clean off the remains of the protective film over the front panel.
I credit this addiction to Paul of Mr. Even if you are familiar with solid state electronics, do not try this unless you really understand the risks involved with working on Vacuum Tubes and High Voltage DC and know the safety procedures to follow.
Eico: eico model 950b bridge construction
This unit you simply increase the voltage a little at a a time while watching the eye tube to show the capacitor under test is taking the charge.
Eico 955 Manual
I am a Electronic Tech. The power supply has essentially no ground, it uses the one resistor from the positive terminal to ground to divide the potential so that the correct voltage appears across the eye tube and the rest of the voltage appears across the capacitor being tested through the rest of the circuitry for DC. Knowing no 950n, I replaced a ejco caps in the bridge circuit with orange drops.
You can see the first light eicoo, after so many years, still on 60V power. I contacted the seller and he was a TV repairman from Massachusetts. This website discusses repair of electronic items. Jun Sun 16, 8: All of these models are almost identical in functionality and circuitry.
You NEED precision reference capacitors to achieve an accurate capacitor tester.

The voltage equalizing resistors across the seriesed replacement electrolytics may be disturbing the DC voltages. You are commenting using your Twitter account.
If you have some new caps on hand that are slightly lower in value than what is needed, you can select caps to add up to the necessary values.

From date codes, this unit was made in ’63; 950g, it seems that this model was made for many years. Shaktimaan all episodes in tamil torrent. What it means, what to look for, etc.

Jun Sun 16, 4: As you mentioned the leakage tets function is a really valuable function that is not found in many capacitor testers today. You are commenting using your WordPress. I don’t think it eio necessary to change the caps in the bridge section unless that range is inoperative or way off.
I believe it is a Hay bridge. PF was added to these testers years ago before high efficiency electrolytics came around, and servicemen noticed bad filters tended to get hot. We do not provide free personalized troubleshooting. This article discusses repair and calibration information for a number of vintage capacitor testers that all use the same fundamental test circuit. If the shadow does not open very far, or it appears blurry or out of focus, then you need to start changing ejco bridge caps out.
I’m not sure how long the shaft is on your potentiometer but I’ve got this pointer in my junk box if you’re interested. So I started fixing it. Users browsing this forum: Just out of curiosity, I’d like to know when Eico finally discontinued this model.
