Thanks Robert, I stumbled into that just yesterday. I already spent about $13 for replacement parts that are on their way. Hope they are the right ones! But I'm also going to buy one or more of those $4.95 jobs. That's just too good to pass up.

Just get a solid +5V supply and a 9VAC transformer, like the old filiment transformers. You might even find one at Homedepot for the doorbell or furnace. We are loooking at taking ionly 5v and creating a 60hz 9VAC from that also.
HOLY FRACKING POOP!!!! I just pulled an original C128 Power Supply out of the box and was blown away at how big and heavy it was. Time has definitely softened my memory, I remembered the supply as a lithe little accessory, barely heavy enough to hold down paper and easily hidden behind your desk stapler. A true testament of just how macro the switching supplies of the day were.
Can you imagine if I had to have another 1.2Amps for the Z80 Cartridge? >:P
Well, got it fixed! Replaced 2 transistors, one 120K 1/2 watt resistor that didn't look burned but was open, and replaced all the electrolytics for good measure. As Robert said, I could have replaced the entire PS for less, but it was the principle of the thing! So my spare 128DCR is now powering on properly. Next to test and make sure it actually works, the 1571 is working, etc.

At $4.95 plus shipping, this exact replacement is good --

The C128DCR also needs a 12V line, in addition to 5 and 9.
Can't forget its built-in disk drive,

:) I see C128 p.s.'s regularly, and their size and weight seem normal to me. ;)

:) Heh, these days I find that paying more cheaply wins out over principle.

Excellent! Unfortunately I have seen parts get replaced but no fix. Now I have to warn you, I got hooked on electronics after I fixed something. >:)
FWIW, C= repair tech Ray Carlsen can now replace the internal power supply of a C128DCR with an upgraded one made of modern components.
