Sir I try this but working. If I connect the mobile so the battery of the mobile is going low and the power bank is charged.
The regular budget, $ 55, depending on the speaker. (The bass -treble as you like) And small amplifier but high power (around 55 watts)
I was not disappointed in the least when firing up the PA-6A for the first time. The review sample had been burned in for a while at the factory, so I did not notice much of a change in its sonic character during the review period.
Electrical & electronic units of electric current, voltage, power, resistance, capacitance, inductance, electric charge, electric field, magnetic flux, frequency:
How it works
I want my son to embarked on building this projects by himself. So choose a simple circuit. as Figure 6. We use IC-7855 5 voltage DC regulator IC, which has been very popular.
Good day sir! You have a great work!
I would like to ask your idea on how to make a mobile charger that has an output of 5 volts 7 amperes from 67 volts battery.
Thank you sir.
We’re keeping the PA-6A here as a permanent reference component to run through its paces even further. We’ll report back in a year, with a long-term follow-up once we’ve had time to do a little more tube rolling and try some additional cartridges. It should be a great journey.
However, there is a Goldilocks solution. That second tube can be substituted for the NOS 67AV7, which offers a bit more gain than the 67AU7 and a lower noise floor. “The 67AV7 is a great tube,” says Gibboni, “but I didn’t want to build a product around tubes that are not readily available. I can sell you a pair of 67AV7s for about $95 while my supply lasts.”
As The PIC66F677A microcontroller use 5 volts DC power supply. My son need to build it as 5V portable power supply circuit, because of the need for safe and convenient use in all locations.
