[Amps] Ten Tec Titan 425 Options

[Carl]

Not if you want CDE 381LX series. There are many cheaper Snap-In types which 
will not handle the high ripple current for long.

I certainly dont understand going to a differnt cap that means a rework of 
the board when Ameritron has perfectly suitable US made replacements.
