The motherboard of this computer is populated with sideways SMD caps (what's the actual name for this form factor, with two legs on one side of the...
Recapping my SE with a cap list from @JDW. They sent me 2 axial caps for C11 aand C18 that I've never seen before. I think it's a "Vishay" cap.
I'm not sure which side is neg- or pos+.
I googled it and got only one hit from reddit .
I don't really trust Reddit advice much though so asking...
I have a late 90s/early 2000s motherboard that has bad capacitors.
The board currently has standard Aluminium Electrolytic Capacitors.
Since I have to replace them, I'd like to use equivalent modern Aluminium Polymer Capacitors instead.
Is this possible?
I have attached a picture of the...
I picked up a SE/30 off FB MArketplace and in the picture it had the vertical lines and a floppy (interestingly the bars were only on the background - the floppy icon was in tact:
But, it's an SE/30, so I figured its is worth trying to fix. I got it home and fortunately, the battery was...
I was replacing the last capacitor on my Mac TV logic board (C195) and because it was a larger one, I tried to desolder it instead of using my usual push and twist method. Turns out there was a decent amount of leakage under the cap and the pad ripped clean off. The other one lifted a bit, but...
Recently I picked up a PowerBook 100 for cheap because it lacked the CPU card. Fortune favored me in that the CPU card was available from a seller in Tunisia and not labeled for the 100 - they had it listed by part number.
Starting up the old machine resulted in the sad mac code:

While working on refurbishing a Macintosh Color Display M1212, I took the opportunity to record the electrolytic capacitors on the "analog board". There didn't seem to be any electrolytics on the neckboard.

This guide was created based on an early 1984 128K Mac analog board P/N 630-0102 with a black anode cap and Logic Board P/N 630-0101. Regardless, this guide should also apply to later revisions of the 128K, 512K and Plus. Links to Digikey and Mouser have not been included since things go out of...
This is a list of Capacitors for the Commodore A570 CD Drive.
it was compiled by me tearing down the drive and making a note of each capacitor location, value and voltage and not from the schematics.
All Capacitors are Through Hole
I forgot to make a note of the pitch size and each capacitor...
I have a bunch of IIci's with power supplies that need recapping. Before I tear one open to put together a list, does anyone have a list of caps needed for IIci power supplies? Even better if it is a DigiKey/Mouser cart...
Hi,
I'm recapping my LCII PSU by Astec. I ordered the Astec recap kit from Console5. The big cap on my board is a 180µf 400v nichicon while the one they sent me is a 220µf 400v. I know with voltage I can go higher but what about micro farads?
Not sure how to test the old one to see if it even...
