[AT] Battery Charger recommendations

[Cecil Bearden]

Dean:
If your old one still has a good transformer, you can upgrade it to 
solid state rectifiers.   The old ones had 2large square diode plates 
that would go bad if they got rained on.  I replaced them with a bridge 
rectifier or more than one if I needed the amperage.  I used to get them 
from Surplus Center in Lincoln Neb.    If not, them an electronics 
supply, not Radio Shack, a real electronics supply house would have 
them..    You probably should mount them on a aluminum plate with some 
conductive grease to give it a heat sink, or Surplus center had some 
heat sinks also...  I never have had a transformer go bad unless it got 
hit by lightning while it was charging.   I usually could fix a large 
one for less than $25 including shipping...
