Does anyone have any recommendations for a bench DC Power Supply. Does anyone in this forum use them in general and to help with the work on restoring / boosting the Ataris?

I use that all the time. I hacked mine to output 5amps short term.
I also have a much larger version.. Had it ages but never used it yet. Brought it direct from the manufacturer .

Not sure but probably this one..

Thought I got 50v 10amp version.. In any case no problems with my small one.

Forgot they did linear and switch modes.

I built one of these kits early on in my electronics journey, I use it pretty much every time I'm doing anything electronics-related. Pretty decent, but only 2A max. On the plus side: cheap!

Bench Power Supplies is most likely the one thing, that everybody with an electronic background builds himself at least once
Here is mine, which's first version was build during my electronics training 22 years ago. I upgraded it recently with new components, such as torrodial transformer, a 30V-3A linear power supply kit and a display to show current and voltage. I like the old school look about it
And back then I did all the metal work myself, including a (now obsolete) cooling block, hand filed from a steel block to a U-shape... my hands still hurt, when I think about that
My old teacher then said, when we're done with it, we will hate him, but know how to file... and he was right

Thanks for all your suggestions including the home made PSUs.
I wish I had the time to build my own but I have so many projects on the go. it would be fun though
The wish list is growing.
