IF I Print this hinge fix replacement with ABS and bond it to the power book cover with acetone, then do you think I could reduce the size of the “hinge fix”part? I am wondering if it will require a lot less surface area to securely meld ABS to ABS????

For what it’s worth: When I placed my multimeter lead on each end of the capacitor (+/-) I discovered several of my newly placed tantalum capacitors appeared to be shorted. I logged the resistance reading for each suspect capacitor. (If a capacitor is not listed below, then the reading was...

I have a couple of LC575’s MB’s that I am trying resurrect. One gave nothing before recap and now gives gives death chimes after recap and second was working before recap and now after recap does NOTHING! Ugh!

Which other caps are you investigating?

Found the EGRET = U11 I have continuity between those pin on a second 575 LB.

I have continuity between those two points on mine.

Hi Nev, I am working in the same circumstances. I am hoping we might work together. Which IC is the Egret? Following recap of my LC575’s LB and AB (and U/S cleaning of the LB and confirming the AB works with my LC520), I have found potential problems on my logic board: the memory chip...

Thanks for the reply. :) Because third-party manufacturers have produced compatible power supplies, I am hoping to find a source.

Anyone…anyone…Bueller…anyone?

I am searching for the same plugs. No success searching google and calling local suppliers.

I have several 45W A1036 power supplies for G4 iBooks with the 7.7mm/3.5mm round plugs that I want to convert to 9mm/3.5mm round plugs for my older PPC PowerBooks. Ideally, I would make small female to male cables to go between the A1036 PSU and my PowerBooks. Does anyone know the correct name...

I just changed the Mouser project to reflect the correction. For me, the above hyperlink to the mouser project is working and shows the correct list.  Please let me know if further changes are needed. :-)  Bama 

I really appreciate the part numbers.  I have created a Mouser Project / Shopping cart using your recommendations.   If someone will test this link and double check my accuracy it will save future users time by being able to click on the link and have a ready filled shopping cart. IIsi Power...

Hi RJC, Did you find the solution? FYI, I had a similar pattern (?”retrace lines?”) after recapping my SE’s Analog board.   As part of that process, I unsoldered and resoldered the fly back transformer.  I forgot to resolder  one pin!  When I resoldered that pin, the screen returned to...

Awesome, thanks y’all!!! I will purchase the that IC and some replacement capacitors and cross my fingers! :-) Bama

Update: I scanned the 840AV YouTube videos by Branchus Creations To look for screens of the U9 IC.   I was able to screen capture two examples which look to indicate it’s a TI - 2082C.  I was able to find similar on Digi-Key, TLE2082CD...

Newbie alert!   I need your help. If you are adept at reading schematics and choosing compatible parts, then please share your opinion on U9 in the schematic and the proposed Op-Amp data sheet image.  Maybe this sparks a memory of the correct part number...maybe you saw this on another vintage...

I decide to upload a better picture to more clearly display the location. If you have access to a 840AV, please upload a picture of the IC at U9 with the part numbers visible or if you are savvy then please recommend a replacement or where to learn the data for this missing IC.  :-) Bama

Hello All, I need your help to identify the IC part number located at U9 on my 840AV logic board.  I recently purchased this 840 from eBay as not working and I started removing the leaky SMT electrolytic capacitors.  I discovered that the IC at location U9 is missing.  Bomarc schematics appear...

I have two of these adapters.  When I installed one into my PB540c, it would only boot from from the ADTX adapter/drive with externally supplied termination power via an external SCSI device.  My iterations of different dip switch settings did NOT yield success for me.  I sincerely hope that you...
