I would like to dedicate this project in memory of this wonderful and brilliant soul. 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. Rico can write in English language into the forum not only in Hungarian!

Vintage EICO Resistance Capacitance Comparator Bridge Model 950B

So I started fixing it. I still have more to learn about this unit. Show More Show Mxnual. I have put in a new power cord, a new y-capacitor and replaced all the electrolytic ones.

Hi, Nice to see a great equipment being put back to use again. While I wait for eicp precision caps to arrive, I can finish rest of the tasks, replace the last few 0. Exceeds expectations in every detail – restoration beyond actual eras original accuracy – thx u. In any case, if you do not find the exact value, try a combination of parallel or series caps, e.

I am a Electronic Tech. It seems to be one of the most popular units out there.

For Leak testing pot P3 controls the output voltage. 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.

No buttons to hold The think I love the most about this capacitor tester is that you don’t have to hold push buttons in to do a leakage test on electrolytic capacitors. The power factor tester too is also quite handy. Most relevant reviews See all 6 reviews.

Have used two in series to keep the capacitance close to the original and the rectifier tube specs call for a maximum filter cap of 4uF. For a moment I saw it through the eye tube glass. For me the hardest part is getting high voltage wax capacitor replacements like 1.

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 manaul to dedicate this project in memory of this wonderful and brilliant soul. This is how pristine it looked when I picked it up. The basic circuit of this unit is very simple.
