Hi,
Thanks for the advice. That particular PS is putting out too much voltage on the DC line but I have others I wish to use. Good to know about the 5.1v. Others have indicated when it gets to 5.5v then it’s too high. I'll stick to 5.1. One of the things I liked about this device is it has additional inputs for the DC and AC feeds so the DC feed can be replaced separately and I can continue to use a Commodore PS for the AC line. I may end up getting one of Ray Carlsen's power supplies or alternatively I have a friend who designs and builds portable substations (in a 40+ foot container footprint) and the like who can make something up so that is also an option. Given the time to source the bits and build though getting from Ray is not that expensive.
I have a 3 other original power supplies already though so I'll probably end up using those with the SaV64. They are good now but there is always a time where they go from good to not. That’s what I wish to protect against. I've also got a C128 power supply that I understand do not experience the same issue (and no associated C128, just a 128D with internal PS). If I can find an adapter for not too much I may use that as it has higher current and is better for when some hungry components are being driven by the C64. I'd just rather use a c64 PS.
I like the idea of an inline regulator. To limit the voltage to 5v or so? As I'm not sure of the issue that causes the PS to go out of spec I wonder if once the issue has begun if it will get worse rapidly and is a sign of impending further failure? Have you had experience with this? And is someone producing these inline regulators?
Thanks for taking the time.
Mike
