[Central-Electronics] 20A diode bridge

[georgew1lsb at verizon.net]

Good one Larry; I used some HP 5082-2800's Schottkys that I had laying around and they worked well also.  
If someone really wants to stay with germaniums, I'd recommend 1N270's. Similar to the 1N34A but can handle twice the current, and they're also cheap on eBay.No matter how many I buy, they all seem to get used.

I've successfully used 1N5711 Schottky diodes as a substitute. Their 
characteristics are much better controlled than those of the old 
germanium diodes.
