same problem here, my power supply E3614A is missing one knob, Agilent Part nr. 5041-8621
Agilent/Keysight have them in stock (cost euro 1.86) but have to buy 40 to reach their minimum order
Any kind soul , having regular orders with them, would be so kind to buy one and send it to me ? Would PayPal all the cost, of course.
BTW browsing around, I discovered this knob is VERY similar to the 0370-3238 which is mounted on my 6632B In case someone have a spare I could adapt it to my need
Attached some pics with the dimensions of the two knobs
