Download EICO MODEL B RESISTANCE-CAPACITANCE-COMPARATOR BRIDGE INSTRUCTION MANUAL service manual & repair info for electronics. This EICO B bridge can accurately measure capacitance, resistance, and inductance. The B can do various other things, but since the manual is available at analyzer and I acquired a similar unit, the Sprague Model 16 Tel- Ohmike. The EICO B, the resistance capacitance bridge and the . The Y cap was taken from an old SMPS – (C7 in the original schematic).

I replaced 3 capacitors 2 didn’t.

Superb Craftsmanship throughout – well packed – Exceeds expectations in every detail – restoration beyond actual eras original accuracy – thx u Verified purchase: I bought the Eico B to play with.
EICO B – Repair/Restoration – Lazy Electrons
By continuing to use this website, you agree to their use. It is a vacuum tube scope and I need a leak tester to check the caps in it. And Finally, I am all set: The power cord was changed to 3rd pin and grounded earth to chassis. I am a Electronic Tech. I credit this addiction to Paul of Mr. Most relevant reviews See all 6 reviews. Ensure manula are skilled enough to do this.
EICO 950B – Repair/Restoration
There is no preview for this item! You could suffer a fatal electrical shock! I checked the transformer as well in this process and saw the heater glow from both the tube and the magic eye.

I would like to dedicate this project in memory of this wonderful and brilliant soul. This unit was working when I received it. After verifying the schematics, the first test was the tube test, with just the heater power. Fill in your details below or click an icon to log in: If you are not familiar with electronics, do not attempt to repair! Do not run down the voltage fast after leak test on a high value cap. 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.
To find out more, including how to control cookies, see here: I was blown away by how well kept it was, and went there to pick it up and was amazed to see the amount of electronic instruments he had — collections all the way from I wish I had come across this valuable article before.
In addition, some files are archived, so you need WinZip or WinRar to open that files. But remember, a very high value cap can load and burn the rectifier tube. I was looking for a decent heathkit or the EICO to help me restore it when I stumbled upon this little treasure. 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.
They say nobody usually comes for those stuffs anymore. The power mode tester too is modwl quite handy. Leave a Reply Cancel reply Enter your comment here You could google it to find more details. Hi, Nice to see a great equipment being put back to use again.
So I started fixing it. The basic circuit of this unit is very simple. I contacted the seller and he was a TV repairman from Massachusetts.
Eico a This unit was working when I received it. I added a line fuse and replaced the line cord with a polarized one.
As you mentioned the leakage tets function is a really valuable function that is not found in many capacitor testers today. Good luck to the repair! I have put in a new power cord, a new y-capacitor and replaced all ekco electrolytic ones.

For Leak testing pot P3 controls the output voltage. I was checking an electrolytic V uF cap and rand down the voltage pot from V to 0 and saw some blue manuall from inside.
While I wait for my precision caps to arrive, I can finish rest of the tasks, replace the last few 0. You need not order the exact value as per original spec, as it is rare. You just need to keep the ration capacitance ratio the same. Remember rules for series capacitors.
