Just replace with a 1N4007 and everything will be fine.

Somebody here said something about having a cross reference for all 
the Heath part numbers.  Can anyone tell me the specifications for 
the Heath part no. 57-27?  It's the diode used in the HP-23 power supply.

Seems like the previous owner of this Marauder of mine ripped out the 
power supply and rebuilt it to look just like the HP-23 including 
putting in the HP-23 power transformer and voltage doubler 
circuits.  Totally undocumented, of course, except I was able to 
trace it down starting with the Heath number stamped on the power 
transformer, which turned out to be the HP-23 power transformer.

This is going to be fun!  :-\
