I was looking for a decent heathkit or the EICO to help me restore it when I stumbled upon this little treasure.

This article discusses repair and calibration information for a number of vintage capacitor testers that all use the same fundamental test circuit. So far, I’ve replaced all of the non critical paper and ejco capacitors.

Leave a Reply Cancel reply Enter your comment here Receiving an electrical shock is not fun and I always take steps to avoid it. I have put in a new power cord, a new y-capacitor and replaced all the eco ones.

Ed Engelken, Google eco and 8 guests. PF was 950v to these testers years ago before high efficiency electrolytics came around.

Repairs should only be attempted by a qualified technician. Do not run down the voltage fast after leak test on a high value cap. Jun Sat 22, 7: I am ordering pF, pF, 2. The next step was to do a complete physical inspection, look for broken parts, shorts, missing cables, broken connectors and so on.


This is how pristine it looked when I picked it up. Other values of precision capacitors are available by request. Jun Sun 16, 4: Ever since CRTs are out most shops have it stacked somewhere in corner and the guys in the shop usually ask me to go through the section where they keep the old stuffs.

Recently I have begun what might be the start of a nostalgic journey in vacuum tubes. If 95b 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 be gained by changing them.

I credit this addiction to Paul of Mr. I bought the Eico B to play with. Knowing no better, I replaced a couple caps in the bridge circuit with orange drops. In any case, if you do not find the exact value, try a eiico of parallel or series caps, e. Dec Mon 31, 7: Most relevant reviews See all 6 reviews. Since I have a digital capacitance meter, this is really not a big deal; but, I still like my equipment to be right.

950v What it means, what to look for, etc. I was checking an electrolytic V uF cap and rand down the voltage pot from V to 0 and saw some blue flashes from inside. I’ve checked with Mouser, Newark, Digikey, and Allied. Here is the long pointer knob on a May we help you read better. Hi, Nice to see a great equipment being put back to use again.
