[Coco] Benchtop Power Supply Recomendations Requested

Tue Jun 2 02:24:48 EDT 2015

One feature that I found very useful and I lost when my first one died was current limiting.

My Heathkit two variable outputs plus a 5 V one needs contact cleaner to make one of the variable outputs work.

The voltage and current analog meters I used a lot. Some sort of meters I would require.

It depends on what your electronics experience is. I have built ~ 13 Heathkits.

For a single output I would look for something like that and it has current limiting.
