Retro Friends, is there anything I should watch out for with with regard to to electrolytic caps vs. tantalum caps? It seems like they are effectively interchangeable.

Interested in working as it should rather thanbeing period accurate.

I'm starting to buy tools and supplies to repair my #Vintage #Apple #Macintosh #LCIII by replacing the electrolytic caps.

I am considering the tantalum cap kit from Consoles5.com.

@AlanGrassia I pretty much always use tantalums when possible at this point. I haven’t been able to find any about the electrical properties that says you shouldn’t replace electrolytic with tantalums. I like that if a tantalum dies, it dies short which will just prevent the computer from powering up. Whereas if an electrolytic dies, it starts eating your board. Also, if you decide you need help with this project feel free to take a ride up!

There's an old junk board that I want to practice on and see if I can pull some chips, sockets, and caps from.

I may take you up on that offer. I only have the one LC III board and I don't want to mess it up right out of the gate.

Let's see how I do on the practice boards and that SP][SD I picked up.

@AlanGrassia @BigBadBiologist I have exactly the same computer that I want to recap but so far lack the skills. What’s your method/tool for cap removal?

@dotsandlines @AlanGrassia I use hot air (380 degrees C). I did a lot of it on this stream if you want to see a lot of decapping action: Starting the preservation of Macintosh IIsi, LC, LCII, LCIII, Performa 400, LC475, and Quadra 605

My hot air kit, flux, tape, and desoldering wick arrived yesterday.

Now, the hard part, finding the time to work on the practice board!
