BE-5

[Robert Groh]

To repeat what Jim said, if we (i.e. potential design sources) had ready access to a BE-5 manual, we could probably give you some straight forward ideas right off the bat.  But that (free access to Heathkit manuals) is gone.  Drat.

What you might do is make an electronic copy of the manual available (or at least the important parts - schematic, circuit description and specifications) so we can have a shot at it.  It is probably a very simple change - just put either a big bridge rectifier package in there or simply 4 big silicon diodes.  Purely guessing here but I would think you probably need diodes with 25A capability and 50 V reverse voltage capability. I believe selenium rectifiers have a higher forward voltage drop.  I'll take a quick look at Mouser for parts and the web for diode data and get back to you.

I am finally getting around to fixing up a Heathkit BE-5 Battery Eliminator that
I bought a number of years ago. Given recent events, it's also fortunate that I
found an original copy of the manual at the same time. I once saw a site that
had a rewire of this unit using a bridge rectifier to replace the original
selenium rectifiers. Unfortunately, this was bookmarked on the last computer
and the bookmarks didn't make the transfer. Anyone know of this site or have an
idea of how this was done?

Thanks

Bob
