Hello good I have been looking for a couple of 7812 and 7512 for 3 days to manufacture a source but for more than I look for it I don't help them there are only 7905 and 7805 Already disassemble 5 PC sources and do not carry them ask in local electronics and are sold out So I want to know what their similar ones are based on other brands or types and since the PC power sources carry voltage rectifiers after the winding that gives the voltage but this does not help me I hope and give me a hand what can I do to replace these 2 Thanks in advance I update: While looking for the possible substitutes proposed I found the source faith an old hp work station that had just what I needed thanks everyone for your help Annex photo of the unattainable
