I'm currently working on disassembling my Macintosh SE FDHD. I would like to recap it. I've heard it's recommended to recap the analog board and the power supply, is it also recommended to recap the logic board? Also, does anyone have a capacitor list and maybe recommended replacements? I'm not familiar with what the Macintosh SE FDHD requires, but I have no issue with the actual process of replacing capacitors.

Re: Macintosh SE Capacitor replacements?
mac logic boards use mostly solid caps, you leave them.
although i would check that varta battery. -

I found this thread https://68kmla.org/forums/index.php?...d-be-recapped/
I agree I would leave the axial caps alone unless you see crusted leaking from them. I have a SE I opened up 2 years ago, caps looked fine so I left it alone, however I did lube the floppy drive eject mechanism, that would be a good idea if you still have it apart. ditto the pram battery, vartas were the better pram batteries along with tadiran. luckily its not a maxell as ive had one ruin a centris 610 by spilling its guts all over the logicboard.My Computer: AMD Ryzen 9 3900X, Asrock X370 Killer SLI/AC, 32GB G.SKILL TRIDENT Z RGB DDR4 3200, 500GB WD Black NVME and 2TB Toshiba HD,Geforce RTX 3080 FOUNDERS Edition, In-Win 303 White, EVGA SuperNova 750 G3, Windows 10 ProComment

Title:
Capacitor detached from PCB – RTX 2070 Super Founders Edition
Description:
During maintenance on an RTX 2070 SUPER Founders Edition, I found a capacitor lying on my desk after reassembly.
I did not notice it detaching, so I am unsure of its original location on the PCB.
Procedure performed:
- Removed backplate
- Cleaned heatsink and PCB with isopropyl alcohol + soft ESD brush
- Reapplied thermal compound
- Reassembled card
Observed behavior after reassembly:
- GPU powers on and operates normally under... -
taken from my thread about car alarm siren here: https://www.badcaps.net/forum/troubl...rm-siren-issue
there are 2 caps which im looking to get replacements for.
Branded as Gemcon
single 100uf 16v 6.5mm x 11.5mm
single 100uf 50v 8mm x 11.5mm
lead spacing is around 3mm
there is space for 16mm tall caps
rs components is good place for me to go since its close by, what replacements do you suggest and do these need to be low esr?
the caps have... -
I found my old Xbox 360 in storage and opened it up to see if there was anything that broke since it was built in 2006 (launch era Xenon revision, never red ringed, never been serviced) and didn't want to find out by releasing magic smoke. Upon moving the dust bunnies out of the way I was greeted by a bunch of capacitors with crud coming out of the top; it doesn't seem to have leaked onto the board so at least I have that going for me.
I'm posting here because I want to try to source replacement caps myself from Mouser or Digikey instead of braving eBay or waiting for places to have... -
I have acquired a used Dick Smith Q-1760 power supply - although the OEM is Manson Industrial
It has at least one problem.
The voltage control potentiometer VR2, 50K is faulty - going high resistance / open circuit in the CCW end and leading to the output voltage jumping around.
I have already ordered a replacement potentiometer, so that's not an issue.
Now, I want to replace all three electrolytics on the PCB as they are CapXon and I don't trust them so much, I will replace them with something better while I've got the thing apart anyway.
All are CapXon... -
I replaced some capacitor which is located on optical pickup pcb which is shown in the table below(PCB #2).Because it have been out of order.
Now,It works very well,But I just have found that all caps (6svpc100my and other part number as well) ,which is shown in the table below, has ultra-high ripple current spec.
It is not able to obtain any capacitor which can be a substitute for this ultra-high ripple current nichicon capacitor.
So I replaced it with samxon and rubycon's general capacitor(GP,YXA series).
I know that these capacitor will not last as long as nichicon capacitor...
