Substitute for LM7912 to get 14V

Ok , so far so good. I bought two of those supplies to have a spare. I may try to fit LM 337 circuit in the next one. SMPs is followed by local regs so I don't think regulation issue will be a problem. It solved the issue I had with CD transport loosing lock. Being happy that I tweaked SMPS to +14V and +6V I didn't check if the negative side will follow , simply assuming so . Player worked for 20 min and gradually signal starting to distort and DAC was loosing lock. This after I congratulated myself successful repair . Thanks Again
