 whoa whoa whoa everybody check it out we get the two biggest crts i think i've ever seen in my life a couple of Mitsubishi 40 inch crt televisions here and look i'm sorry you might hear a little bit of background noise i am at the museum of fine arts here in houston and we're doing a crt class and that's catheter a tube class of course and so i just wanted to show you some of the amazing crts they have here starting with these unbelievable Mitsubishi's first let's just look around the back we have the Mitsubishi CS40307 120 volts 60 hertz 199 watts this is from may of 1996 we have coax for vhf and uhf and then of course just a couple composite video inputs as well as s video so look at that yeah there's there's something about purity where you can tell this whether the tv's facing north south or neutral to kind of help your your purity because these tubes would obviously need a lot of good degausing and could easily be impacted from the difference in size of the tube and the magnetism can definitely get into the picture but i've already got a super nintendo here with s video coming out of it and we're going to turn this tv on and get a good look at it to see how it looks this is a very dirty one we've got power volume channel input and there's even an extra degausing button on there and an av reset look i've already got the 240p monoscope pattern pulled up and just check it out i didn't think that wow look at that geometry it's actually not half bad for just firing it up it looks really good i'm really surprised by that all right so up here in the left hand corner we can see some obvious purity issues so that's what that switches there for to help you clear up the purity and not end up with that kind of a glaring purity problem where the colors just changed over here in this upper left hand corner pretty good linearity huh not bad we're going to get in here real quick and look at the scan lines on some video games well so the screen looks pretty great but we still should try to do something about this purity let's try to use the external degausing wand see if we can't get it to clear up a little bit still not one to really clean up it's like that's the best i've been able to clear up so far well everybody there's the second one it's a little bit cleaner and it still has a little bit of a purity issue not as bad as the first time that's definitely the biggest problem with this size of a tube is getting the interference cleared up you saw when i tried to do with the other one i was still having trouble even with the wand if you just look at the stands it actually this person who originally bought these did have a stand system built and actually these custom boxes for it because he was using them as his promotional pieces for businesses this is sticker right there from california and after he closed up he sold these to the museum and they have those cool custom wood plates at the bottom to hold them in place and then you could sit there and take a forklift actually and lift this up and set it on top of these two boxes at an art show or display or something so that's a real reasoning behind them but really cool stuff as mitsubishi's they come with remotes if you ever see one of these and you want the biggest shadow mass tube this might be your chance and i'm just really thrilled to get to look at them thanks for joining me today if you're interested in learning more about the houston trip i took out to the museum please check out my podcast the cathode ray podcast i do on the zezz retro channel that's my buddy zezz and myself otherwise i'll see you next time everybody
