| My poor mans SMU - The Agilent 66311B |
| << < (10/41) > >> |
| GAD:
I got mine today, and it's in rough shape, and did NOT come with a knob. Technically I believe I could return it because I specified my offer with a knob, but for the price I paid and the price of a knob I'm not sure I care. I'll take pics in a bit. |

Opened it up with the service manual at the ready. It turns out that there is a spare jumper installed on the transformer! I pulled it, rearranged them accordingly, let it sit a bit, then fired it up and it works! The fan fired up, it self-tested, and is chugging along. The fan is noisy and needs to be replaced. This unit came not only without a knob, but also without a back bezel. The only problem is that the VFD is so dim as to be practically unusable. I was mildly amused because it's got 110V scribbled on top (It wasn't), and "powers on - takes 30 seconds" on the side (it didn't). Pics: |

The spare jumper is cool - I mentioned it a while back. No rear bezel and a dim display doesn't really seem fair though. The dim display can perhaps be overlooked based on the listing but the unit should have been complete without missing hardware(other then the knob). btw - when changing from 220 to 110 you're also supposed to install a 3.15 amp fuse. I installed a 3 amp fuse when I did the change. |

Listed as orderable for $19.01 if you can actually order one. I haven't ordered any Agilent/Keysight parts in quite a while. Not sure if I would bother replacing it myself. Maybe I would if I was also going to order a replacement front panel knob. http://www.keysight.com/my/faces/partDetail.jspx?partNumber=03478-88304 |

I misunderstood your post and thought that you asked Agilent for a jumper which they sent you for free. Rereading it now I see what you meant and must have completely spaced when I read it the first time. The auction said "for parts or repair and is not working properly". It also did not show pics of the back. I doubt I'd win a dispute, and it was only $55 plus shipping, so I may just keep it and see if I can push the VFD back to brightness for a while or maybe just offer it up on eBay with an honest condition report and see what happens. I was surprised at how heavy it is. |
