 I guess they were past that by the 3610 days? My HP branded 3610 has red, black, and green for the earth. Unless a prior owner changed them, but they look the same age as the rest of the case.

It was a change made during production. It happened sometime before the name change from Hewlett Packard to Agilent. There were other cosmetic changes made as you can see. You can find HP branded ones with the three color binding posts and the lighter color scheme, but they're not all that common.


rrinker:
 Actually, mine IS the lighter color like the Agilent one, but with an HP brand. I'll have to nab a picture. The spacing of the model number and specification line is in between those two - the "0-8V" part starts on the middle of my display, not over by the Amps label like the HP one and not so far to the left as the Agilent one.

Radio Tech:
This is probably my most used PSU at the time. It is a Harrison Laboratories 6263A.
0-18 volts
0-10 amps.
Made in the early 60's and still works like a charm.

rdl:
I prefer the later styling as seen on Agilent 3610 (and other) power supplies but for some reason want one with the Hewlett Packard name on it. I check ebay off and on, but haven't found a good one at the right price. It's possible they only made them that way for one model year.
