I put those extra transistor base connections/pads there for alternate transistors in the prototype. I was at one point going to use...

So after seeing the built up prototype, I was motivated to take another look at the regulator and as suggested, I looked at my Dazzler...

Ah... seeing the actual prototype is quite helpful. :) Here is the update. The only other thing I changed was to eliminate the two pads...

Cool !

I looked at several datasheets for TO-220 regulators, all seem to specify a max of 6.35mm length for the wide portion of the pins. The...

So at the moment, I have the holes plated through. Apologies if I missed it, but is there a specific reason as to why they shouldn't be...

Yeah it probably is fine but really triggers my OCD anyways :ROFLMAO: thanks again

Angles converging on a pad like this are generally fine, but changed per your request:

Updated with labels for external connections and proper TO-220 footprint.

I intend to build a couple of these as well... very neat project. So here is a variation with pad sizes that are a bit more suitable...

They are close together, but when scaled the pad sizes seem to match the original jpg that was uploaded. I should probably reduce the...

Attached are the gerbers for the JS-1 board. I added some identification text, and filled in the junctions at C5 and Q1. No problem...

Falter, Daver2, Al Kossow, etc: I just stumbled across this forum, and it brings a nostalgic tear to my eye. My father was Bruce...

Ahh... sorry about that. The diodes were a bit difficult to discern. One more for review... I'll upload the gerbers when you give the okay.

If this works, I can upload the gerbers.
