[sdiy] Free stuff - ideas? Also, ringmod schematics?

[John L Marshall]

I use 12V automotive amplifiers and amateur radio equipment. I power them 
from a 100Ah gel battery. You could could use any "deep-cycle" battery to 
power your equipment. Only a small battery charger would be required to top 
the battery off between uses.

Take care,
