Hagen must have used a time machine to set his high score, in 1864! 

To put a little weight on the other side of the scale, I have also been thinking about replacing caps (elco's, a much better word IMHO) on vector PCB's and monitors with hi-end audio quality one's.

I know this may sound stupid, but at least the amplification stages of vector monitors are very comparable to audio amps.
However, I checked the PCB vector stages and they actually don't have any (or not many) elco's at all....
The monitors do have some of course....

If it would (further) improve the picture quality it's definitely worth trying...

In my amplifier restores I mostly used the Matsushita/Panasonic FC series (for the elco's). These have low impedance and thus they are great for audio purposes, and they are affordable too . Unless you want to upgrade to the really expensive audio specialty brands of course. I looked into these for my restores but I figured the price was too high, take maybe 5x more expensive for 1.5x quality gain. I was still on a student budget so it had to be relatively cheap Although I still would buy the FC series now if I could it all over again. I'm very happy with their performance. If it was a tube amp I would go for the expensive stuff.

I also replaced a lot of polyester caps with polypropylene. I know these don't dry out like elco's, but they have more gentle characteristics. Which is great for audio

Hmm, how old are they?

At least that's what Bob said, I suppose, what do I know? 

It's of course possible that Bob had them special made, I'm not questioning what he told you . It just seems weird that he had them special made when they already exist.

The caps from digikey are not going to be very old, and they are still in production (so you can order a brand new batch from the factory ). Digikey just doesn't stock up much on those uncommon caps. I ordered a few of those large can capacitors a while ago (not that type I linked to) for those old amp restores and the oldest cap was about 8 months old (date code on cap).
There are more types to be found but they are going to be smaller than 50mm diameter mostly, because over time all discrete components get smaller due to new materials, production process,..

It's supposed to be 27000µF/15V, but according to Bob Roberts anything between 27000µF and 35000µF is OK. You can also buy a higher voltage one, never lower!

Aha, so you just have to add a couple more 74's and you're done building your Dominos FPGA

Indeed no emulation is the key for me with this technology. And instant on, like a real PCB....I really don't like arcade games that need to boot....sorry.

Well, you've got me thinking....because of the economic crisis I only have to work every other week now, so an arcade related project would be cool.
So I looked up the Dominoes manual and there is a microprocessor page in the schematics. I don't know what cpu it is, the pages are hard to read (scan quality). It's part 90-6009. I really would like to give a game reproduction a try, but not with a microprocessor to start with .

The 250W on the converter means it CAN deliver UP TO 250W, so it only delivers the power you need. For instance, if you need 130W total, the converter is going to deliver only 130W.

YES, if this is possible, you should definitely try that next time!
