I didn't know about that. Of course mine are both about 40 years old.



Hell, my Eico 6/12 volter is older than that and uses a selenium rectifier.

Used it just last week when youngest son's 95 Honda's battery got
discharged because water got into the underhood relay for the AC clutch
and created a path between its hot contact and the end of its coil which
backfed juice to the coil of the heater fan relay which kept that fan
running until the battery died. Took us nearly three hours to figure
that one out. He can live without an AC clutch relay until the weather
warms up. G

I used to have a charger with a tungar tube rectifier in it, but someone
swiped it....
