Thanks a lot. You are an excellent teacher. Explained step by step not fast at all. Great. Look forward for many more. This js my first experience with you.
For the 20kV diode you checked last, why couldn't you use a DC power source instead of a transformer? Also, why didn't you flip over either of the high voltage diodes? Thanks much for the GREAT video!
I dont think id use the led tester. All of my diodes read the same voltage drop except for one, it must have had just a few internal diodes gone bad and had a voltage drop of a few volts less, I believe it was underperforming compared to the others and it wouldnt have been recognized with the led test.
I am a new Sub after watching this great video and explanation. Love the last tester, going to make me one now. It looks to make testing hv diodes fast and easy.Thanks for sharing. Just1
Thank you so much Sir for sharing such a valuable information. Just guide me with I want to replace old diode which is R 360 pls suggest me with what suitable value diode can i replace Awating for your response from India And God bless you
You can’t. You need to make an oscillator circuit to drive a transformer off of a dc power supply (a battery or rectified wall power, any dc power source you look for) and then rectify the output of the transformer
Why do you need to add a 3.3 KOHM resistor in series for the circuit to measure the diode voltage drop? Can’t you just connect the diode directly to the voltage and measure? Or you want to limit the current to try and save the diode
Some simple early radio receivers used a "cat's whisker" diode which has a point contact between a fine wire and a suitable crystal (not bonded). Try searching that term or crystal radio, you might be able to make one quite easily!
