Heathkit HP 23 Power Supplies

[VE3FWF]

The PS-23 and the HP-23 series powers supplies should all work with your 
SB101. The low B+ supply on some versions have a switch to allow the power 
supply to run on with the HW-12, HW-22 and HW-32 series radios which require 
a lower voltage on the low B+.  There is also a mod on the HW-X2 series 
where you can use a resistor to drop the low B+ voltage while using the 
higher voltage B+  from the power supply.  Some versions of the HP-23 
require you to manually rewire the tap on the transformer to change the low 
B+ voltage.   Best to check what the voltage is before you use the power 
supply. Some versions also have an adjustable bias supply (which I believe, 
was never required);  Heathkit just omitted the adjustable bias supply on 
the PS-23. BAMA has the manuals so you can verify specifics.
