[Heathkit] HP-1144 PS

[Joe Hatvany]

To the list

Does any one know if  I can find a source for parts to upgrade the(  HP-1144 
PS to a HP-1144A ? As it happens my HP-1144 does not have the crowbar 
circuit included, on the regulator board an did some nasty things to my 
SB-104A's "A" & "B" boards, and possibly rhe Output Transistors when the 
un-soldered   ground pin came loose from the regulator board. (poor kit 
building )
Any and advice will be appreciated

Thanks &73
