I am looking into overhauling the analog and Sony PSU's. I am thinking of replacing the capacitors for both units. Any advice on what other components to replace, such as transistors, perhaps upgrading them with better parts? I will also see if I can find a NOS flyback transformer.
Regarding the Sony unit I am thinking about replacing the internals with a small form factor PSU. My intent with replacing the Sony internals is to hopefully supply the logic board with more power to support various upgrades/add-ons with greater stability. Any EE's out there have advice on what to look out for when selecting a replacement power supply? The main issue (besides unknown risks to doing this) is it is tricky to find a supply with 2 separate +12V rails, along with the other voltages, that is not too big or too expensive. +5v = 6.0A +12Vsweep = 1.25A +12Vdisk = 2.1A -12V = 0.5A Here is an example of the type of PSU I am considering (does not have truly separate +12V rails): http://www.hardwaresecrets.com/article/Seasonic-SS-300TFX-Power-Supply-Review/1021/2 I am aware of the dangers of working with high voltage equipment.
