How to make a 3 Dollar Battery Charger
" I used to have a pal called OXO, Jim G6EQK, who used to use something of
a
similar device to the 3 dollar battery charger on TV tubes when they went
flat.
In fact this is how a lot of early 'live chassis' 405 line TVs worked,
except that they used a resistor in place of a light bulb.
