Do you realize that your measurement device also need a battery replacement? Some might not aware about this. Not only your digital device, but also your analog “needle” based measurement device. They do need battery replacement. I bought this Sanwa...
Some people send me an email asking about how to measure cathode current and resistor rating. I will show you how to do it and actually this way is not only applicable for cathode resistor (but commonly used for that...
My Sanwa PC510 multimeter has the capability to measure the temperature via small probe. So, I’m curious to measure my tube glass/surface temperature. I test the 6N1P, 6N6P, and 5U4G tubes....
On this lazy new year, I do a comparison between some of my old cheap meter (for Capacitance and Multimeter) and my new well know brand, Sanwa. I finish some measurement for Capacitor and Resistor. It seems even the old...
Still remember the Extreme Capacitor Battle article? Well, it’s not done yet, but we are very close on it. The break-in session has reached around 180++ hours. I can feel the characteristic from each capacitor. To simplify (and easier) comparison...
