BE-5

[Comarow, Avery]

If you can get by with just the schematic, I'm pretty sure the BE-5 was
produced during the era when Heath included schematics in their
catalogs, and if so, I probably have the catalog. Let me know if you
want me to check.

Happy holidays,

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
