You need not order the exact value as per original spec, as it is rare. I still have more to learn about this unit. In addition, some files are archived, so you need WinZip or WinRar to open that files.
It is fun to work with since it 50 years old. 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.
But was lucky it was just the pot. Hi, Nice to see a great equipment being put back to use again. I am ready to head back to my TEK Project.

I contacted the seller and he was a TV repairman from Massachusetts. You are commenting using your Twitter account. As you mentioned the leakage tets function is a really valuable function that is not found in many capacitor testers today. I added a line fuse and replaced the line cord with a polarized one.
The power cord was changed to 3rd pin and grounded earth to chassis. Superb Craftsmanship throughout – well packed – Exceeds expectations in every detail – restoration beyond actual eras original accuracy – thx u Verified purchase: You can write in English language into the forum not only in Hungarian!
I have put in a new power cord, a new y-capacitor and replaced all the electrolytic ones. It can kill you. Email required Address never made public.

I checked the transformer as well in this process and saw the heater glow from both the tube and the magic eye. For Leak testing pot P3 controls the output voltage. 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. Nice to see a great equipment being put back to use again. I have recapped and redone some wiring and retubed the unit.
Fill in your details below or click an icon to log in: As expected, I found broken cables, joints, exposed cabling. After verifying the schematics, the first test was the tube test, with just the heater power. This file is downloadable free of charge: I replaced 3 capacitors 2 didn’t.
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. And Finally, I am all set: 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.
Skip to main content. These free programs can be found on this page: For a moment I saw it through the eye tube glass.
Looking for other manual? Overall a great piece of hardware! Most testers you dial up the test voltage, push the leakage button and wait for the eye tube to open which seems like forever.

And here you go, this is what it looked like on the inside. Recently I have begun what might be the start of a nostalgic journey in vacuum tubes. 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. 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.
Eico a This unit was working when I received it. I have to disclose, I learned this from U-tube videos.
