Heathkit HP-23 Power Supplies

[Guy G. Giacopuzzi]

The power supplies are all basically the same, in that they all put out 
the same combo of voltages...the differences included switches for 
on/off, switches for 250 vs 300 volts for the low voltage section, and 
pilot lights...the supplies got simpler as Heath produced them longer 
and tried to economize them...but they can all put out the same 
voltages...IMHO, there are some differences with the quality of  filter 
caps...some B and A supplies had Nichonin electrolytics, which I thought 
last longer....the only weak spot I've had on them is the HV rectifiers, 
which have a relatively low rating for their service.
