This item doesn’t belong on this page. 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 definitely need to get the 5W 10K wire wound pot from eBay. I am ordering pF, pF, 2.
As the tube heats up slowly, euco 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 9950b low as possible to protect the rectifier tube. They say nobody usually comes for those stuffs anymore. To find out more, including how to control cookies, see here: 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 me the hardest part is getting high voltage wax capacitor replacements like 1. I added a line fuse and replaced the line cord with a polarized one.
I became curious to know more about him. Eico a This unit was working when I received it.
I checked the transformer as well in this process and saw the heater glow from both the tube and the magic eye. The basic circuit of this unit is very simple.

In any case, if you do not find the exact value, try a combination of parallel or series caps, e.
I was blown away by how well kept it was, and went there to 9550b it up and was amazed to see the amount of electronic instruments he had — collections all the way from In addition, some files are archived, so you need WinZip or WinRar to open that files. Skip to main content.
I have put in a new power cord, a new y-capacitor and replaced all the electrolytic ones. Yes, I learned it the hard way. 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 mnual close. I still have more to learn about this unit.
