I'm normally an antique radio guy, but I picked up an early 50's experimental car TV from what used to be Delco Radio. This is a one-of-a-kind set with no documentation, and is missing the picture tube. I would like to restore it to working condition, but there is no point going any farther until I procure a picture tube. There is no cabinet (some GM concept car was the cabinet!), but it looks like it must have taken an 8" round tube. I think the most likely candidate is a 8AP4. So where do you find these? No luck so far on eBay.
