At your own risk. Attention when using batteries. A series specially selected fuse should always be used for safety. Batteries, especially Li-ion have strict charging requirements for safety. All safety precautions must be exercised.
There are great li-ion chargers on the market. One that has been tried with impressive results is the Fujicell.
Your own risk.
Below are at least a few options.
The Pleiadss V6 head amplifier circuit is the following, Cc can be 22nF, the electron tube can be a Nuvistor 7586 too. The Pleiades bias resistor can be 6MΩ. different interesting sound quality can be adjusted by varying this resistor. If should not normally be below 2MΩ.
Solar powered.
3 AA rechargeable or fixed batteries.
One li-ion 3.7V battery. A high capacity battery should give at least half day of continued operation.
One 4V lead acid battery. (Just found out today that 4V or 8V lead acid batteries exist).
Hand crank option. Just joking. But it may power a battery charger.
A great manufacturer of battery holders is Bulgin.
