I had a quite time getting the same CRT module out of my HP 4145B Semiconductor Analyzer. That had most of the screws in the silver front bezel, as far as i remember two screws in the front top and two in the front left side (Its those i missed). Some of these are under decorative stickers and some of the identical looking screws found in there actually hold the bezel to other parts, but the ones around the screen hold the CRT module in. Once those are out its just a matter of two or three easily accessible screws in the back, before the whole thing slides out forwards with next to no force. Some screws around the CRT module are not required to be removed because they just hold the CRT module itself together. But perhaps this instrument has extra screws. |

Yeah, the 3577A is the only one I've seen that has an extra bracket at the bottom rear of the 1345A for attaching to the "shelf". EDIT: OK, sounds like you got it... |

The NewScope-5 is fantastic. LOVE IT. Applied my advanced arts & crafts skills to the foam liner installation: LCD mounted in bezel: Power-on smoke test before closing it up. I had actually forgotten to plug in the main power cable, so good thing I checked... Also adjusted the focus trimmer to pick a color scheme. Also had to move the scan direction jumper to get the image right-side up. Back in use: I had planned to replace the fan while I had it open, and I did detach the fan, but couldn't get it out without removing the BNC jacks and I didn't want to go there. It's possible I could have yanked it out with force. The ONLY thing wrong with the NS5 kit is I didn't get it a long time ago! |

I run the fan mentioned in the first post, so far no problems with it. It is still loud but, but before it was unbarable, now it is about on the level of my HP8753D which is acceptable. We have a sound pressure meter at work, I will try and remember to borrow it to give you some data. |
