Yes . But the thing when he designed this was the primary inductance "L1" a chunky 10mH thing this makes it a LC filtered supply on the primary side before the regulator . The supply is not as dirty to the network as many others . Wonder if his write up on the design idea is still on this forum ? Suppose the Touch has a bunch of internal switchers and regulators anyway . Point of the exercise is that it's nothing magical with power supplies . A linear supply can also be dirty to the network just as switch modes can . This design fixes some of that but the 5 V side could probably have even better regulators if one wants to make it a project of some kind . If it's good enough it's ok regardless of topology switch mode or linear . This design is not super expensive . If I got it rigth ? -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
