[Heath] SB-110A

[Allen Jones]

Don't know if it's true, but I once read that the reason the HP-23 later became a PS-23 was due to a complaint from Hewlett Packard.  They didn't like Heath/Zenith using "HP" once they got into the computer business.

>None of the HP-23- series of power supplies has a switch for "bias"!  The HP-23 and HP-23A have fixed bias and a variable bias.  The HP-23B, HP-23C, and the PS-23 have only fixed bias.  The HP-23A and HP-23B have a toggle switch to switch between 250 VDC and 300 VDC.  The HP-23, HP-23C, and PS-23 require an internal connection to determine if the lower B+ is 250 VDC or 300 VDC.
