Kuuleyn Vacuum Electron Tube Valve Preamp Amplifier Board Headphone Amp Parts Musical Fidelity Kit, 6J1 Audio Tube Headphone Amplifier, Compact Electronic DIY Kit DIY Parts (Static Bag)

【Funtion】Connect the 6J1 tube pre-amp between sound source and amplifier, it will effectively filter digital flavor, the music and human voice will be relatively good.
【Eight 470uf Capacitor Filter】Eight 470UF capacitor filter is very clean, excellent power system to no hum, filaments are powered with DC 12V and need to be connected in series in order to reduce noise.
【High Frequency And Low Proof】A coupling capacitor is an electrodeless electrolytic capacitor with high frequency and low proof.
【Easy To Use】Using DC 5.5*2.1 socket and AC 12V transformer, you can also use AC 12V transformer without a plug, just need to weld the power cord onto the circuit board.
【Can Yourself Assemble Them】This kit comes in parts so you can assemble them together by yourself, enjoy the process of building your own tube amplifier.

It is a series resistor inside capacitor, using 100kHz to remove the impedance 1/(2*pi*F*C)..
The impedance become small, and we can then measure the true series resistor value..
Using this theory, we can measure the capacitor is bad/ damaged or good in condition..
Our ESR meter only applies less than 15mV DC or peak to peak on a good capacitor, as a result we can use it as in circuit test..
During repag TV, LCD, Audio board, etc. we can in circuit testing the capacitor is good or not..
