Mike, I have a couple of these Kodak Sound 8s too. The lamps are very expensive(over $100) if you can find them, but there is another solution to solve the lamp problem. I did a post a couple of years back on performing a lamp mod on the Kodak Sound 8. It's fairly easy and inexpensive plus you get a brighter picture. The new mod lamp cost less than $10 dollars and it's a halogen.
Here's is a link to my post which will show the lamp mod step by step. I got the mod idea from Dino Everette.
