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).

It is a vacuum tube scope and I need a leak tester to check the caps in it. Recently I have begun what might be the start of a nostalgic journey in vacuum tubes. Do not run down the voltage fast after leak test on a high value cap. I had a hard time getting those film caps but dico to get them finally.

EICO B – Repair/Restoration – Lazy Electrons

For Leak testing pot P3 controls the output voltage. You can see the first light up, after so many years, still on 60V eio.

I have recapped and redone some wiring and retubed the unit. 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.

Most relevant reviews See all 6 reviews. Its mentioned in the blog, If you run down the voltage quick after leak testing, the entire capacitor will discharge through the POT and burn it.


I am ready to head back to my TEK Project.

Looking for other manual? Nice to see a great equipment being put back to use again. 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. 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 like to dedicate this project in memory of this wonderful and brilliant soul.

You may also like. This is how pristine it looked when I picked it up. 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.

I have to disclose, I learned this from U-tube videos. Sometimes, in the process of looking for something, you come across a few folks, who possessed a wide spectrum of skills and abilities.

As expected, I found broken cables, joints, manuaal cabling. I eicco curious to know more about him. More items related to this product.

It is fun to work with since it 50 years old. These free programs can be found on this page: You just need to keep the ration capacitance ratio the same.

Notify me of new comments via email. 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.
