Thanks!
Well I got the 270c yesterday and is uses bit different array of caps:
Here is the list:
Logic board:
4x 35V 100uF 10x10mm footprint
1x 35V 47uF 8x8mm footprint
1x 25V 100uF 8x8mm footprint
All those must be 10-11 mm tall or less
1x 25V 33uF 6x6mm footprint, 6mm tall
Inverter:
1x 35V 10uF
LCD has an array of capacitors also, but they all looked perfect, and heating the pad with the soldering iron produced none of the usual fishy smells...
But if someone needs a list of them:
(Sharp LQ9D041 LCD)
6x 47uF 6V
2x 22uF 10V
3x 100uF 6V
1x 10uF 25V
1x 47uF 16V
1x 10uF 16V
1x 33uF 10V
I disassembled it before I powered it on, and also replaced a leaky 10uF 35V cap on inverter with new. Actually I used 3x 4.7uF 50V MLC caps in parallel as I have hundreds of them, and that gives about 11-12uF of capacitance (measured beforehand), and extremely good and low ESR. The capacitance of MLCCs is usually bit on the lower side and also decreases a bit with applied voltage. And those will never go bad.
Also one note, the hinges looked they were coated with some kind of white grease at some point. That stuff was quite hard and lost all of the greasiness. I decided to clean them in an acetone and some carb cleaner, and reapply some white Molycote grease.
Other capacitors on the logic board are also starting to leak a tiny bit as expected, but I had to look twice to be sure, as the leakage is really minor. I don't have exact replacements for those on hand, so I will order them and do them next time. I will leave the LCD capacitors alone for now, the image is perfect.
I was lucky as the my new PB 270c is fully working, despite sitting for the last 20-25 years or so the previous owner claimed. I don't know how, but the original Apple NiMH battery was still at 6.8V before I even first plugged it in, and I charged it for about 30 minutes and then tested it for few minutes and it held. Also the HD sounds perfect.
I only need to find an original charger now, as I was using one from the PB G3
