No i mean the power transformer. :)

I was just wondering what were the model number of the keyboard and mouse that came with the Macintosh SE/30?

Anyone knows where to a get a transformer for a 128k Analog Board? part number?

Anyone knows where to download MacTerminal 1.1 or 2.2?

Do you know any good System .97 disk image?

I'm trying to emulate System .97 using mini Vmac and I notice the FONT difference when it's run on both emulated 128k Macintosh(64k ROM) and Macintosh Plus(128k ROM). 1. 128k Macintosh 2. Macintosh Plus As you can see, the font used on the first screenshot is unusual. Is this because of...

1) is this the upper RFI shield? 2) Which one is the lower RFI shield? 3) is this the 22AWG wires?

On your Google Doc you have this Digi-Key Part Number: PF2395-ND for C1 which should be a 3.9µF(J) NP HF 250V 105°C, right? But the specs for PF2395-ND says "Operating Temperature: -25°C ~ 85°C". Is this ok? OR should i get P13751-ND with Operating Temperature:-40°C ~ 105°C instead? Since you...

What do you mean by "UPGRADING the Compact Mac Analog Board" ? Can i just use the original 128k parts for replacement? via PM: When you say "HF" (High Frequency) on your list, what do you mean by that? i was inquiring at a local electronics store here in my area but I don't see "HF" printed on...

Oops sorry, I mean the two big diodes at CR20 and CR21. The ones with heatsink. How do you check/test them?

Thanks GnatGoSplat! How about the two big diodes at C20 and C21, how do you test them? is it the same procedure as you mentioned above?

I'm trying to fix a 128k Analog Board and would like to know if I can test the diodes and resistors and capacitors without removing them from the board? i have a digital multimeter.

thanks zuiko21! I've already replaced some components and was able to get the board alive though not functioning normally yet. i hear a clicking sound when i turn the board on.

I'm fixing a damaged Analog Board for a 128k Mac and I need to replace some component/parts like transistors, resistors, etc.. My problem is I'm not sure how to buy those parts. I mean I don't know their part numbers or something like that. Any help is appreciated. Especially these parts:

Is there any manual somewhere i can download about part numbers/components of this particular analog board?

Those parts can be easily obtained from electronics stores?

Oh sorry i should have been more specific with my question. Im just really new to this whole vintage Mac and learning a lot from this forum. Guess I was wrong to assume that the 128k logic board picture at http://en.wikipedia.org/wiki/Macintosh_128K is one of the earliest or first editions 1984...

im comparing this logic board to the one at http://en.wikipedia.org/wiki/File:Macintosh-motherboard.jpg and i see some differences. Is this an original 128k Mac board?

What about the transformer? do you think it's damaged?

which one is the power supply? needs to be replaced too?
