Hi A'af

Nothing virtual about it, it's just a battery and a charger built into the preamp, so the pre runs on battery most of the time and charges up when it gets flat or when it's not in use.

I mean exactly not mention that, here "Virtual Battery Operation" really don't use any battery at all

pinkmouse · 15th August 2002, 11:42 PM

What kit exactly is this used in?

Use several farad capacitors then connect them to the op-amp. The op-amp should last for a few months to years with out charging the capacitors again.

Yes, you can use a capacitor instead of using batteries in a pager or beeper. It should last for a few weeks on vibration mode.

Look up BEAM robots and Super Capacitors.

Hello!

The "Virtual Battery Operation" solution used Andrea Ciuffoli and he "stoled" from the Technics (but he confess

). Here is her amplifier the Power Follower 99:

I think the circuit is a through regulator with Mosfet.
