I have never seen one though the cct says LM323K, Which is a 5V 3A three
terminal regulator in either a TO-2220  or a TO-3 case.


Measure the current and if its over 2A then replace the linear PSU with
a switch mode one like RS-15-5 from here

If its less than 2A consider replacing the 3 terminal regulator with
something like this

Then ask your self it the machine is still 'authentic'.
