I can't remember if the 2020 is the one, but one of th Pulsars were actually a Zenith based chassis in a much smaller fan cooled case. Others were Pulsar built, and there's very little available for them. I stripped one down about 4 years ago, but ended up junking the parts when I never saw another one.
THe Zenith based one is fine, I've got one here in a sports bar that they've run the heck out of, and other than weak tubes now, it's still running strong.
By video-only we mean NTSC video only, or a maximum horizontal scan rate of 15 kHz - that translates to interlaced NTSC TV - a maximum resolution of 480i. The shortcoming of this type of CRT projector is that it is not capable of displaying a progressive-scan image, and will have very visible scan lines when the image is blown up to typical front-projector sizes.
I didn't realize that, so obviously there would be no real advantage to get this projector. I mean if it is going to have inferior video quality, even if it was in perfect running order, I would be better off just looking elsewhere right?
Is there anyplace that has like a spec sheet for me to read up on the different types of CRT projector's out there? I thought that CRT's were equal in resolution, I was wrong Oh well, thought I had a good deal for a second.
What about an ECP 4500? Is it worth getting one for less than $100, even if it currently isn't projecting an image? What if I could get a 4100 with it?
I know I am asking a lot of question's, but I don't know anywhere else to ask.
I am learning, yeah!
So if the horizontal sweep is 35kHz or more than I can output 720p, if it is 48kHz or more I can output ALL the HDTV signal's?
So the 4500/4100 at 90kHz and 80kHz are good, right?
And the 4500/4100 both use 7"CRT's so does that make them interchangeable?
The ECP's are great and if you can get two even for parts for under $100 you are starting out in good shape. There is a great depth of ECP knowledge on this board to help you get them running if it's possible.
Yeah after bugging you guys I decided to see what I could find on my own, I stumbled across crtcinema, the specs page they have are great.
From the looks of it the Electrohome are the best $-performance brand. I think I'm out of luck though on the 4500/4100 I may still get the 4100 but it is definately in need of repair, but the tubes are supposed to be good.
Hopefully I will have something develop in the near future.
