I don't know if this belongs here, but I think it might apply to more people than just me. Lains, how or where do I acquire/buy a working CRT TV? Not anything too serious, not for my workstation or anything, just a display so I can play old games with true nostalgia.

try thrift shops & recycling centers also schools throw out ancient equipment all the time

when all else fails, the internet is your friend.

>>16925 Try asking friends, family etc, maybe you can score something nice then thrift shops, something like craiglists

I've had good luck just driving around looking through trash. People throw these things out way more frequently than you might think.

>>16925 Habitat for Humanity "ReStores" might have more CRTs in stock than your local thrift store, people seem to donate there more (at least for electronics) than the local thrift stores where I am.

>>16925 I've seen a ton on craigslist. I've gotten 3 from randomly driving along and stopping at garage sales / junk giveaways. If you know any SSBM (super smash brothers: melee) competitive players, they might be able to hook you up. (non-CRT screens tend to have a noticeable delay that can seriously impact tournament play)
John Titor · 2019-05-04 19:05
I think thriftshops, craigslist, and used electronics stores. They're not hard to find, but it might be hard to find if you're looking for something specific.

>>16925 My grandma has like four or five in her basement alone. fuarrrk are they like some type of rarity now? Or do you just not want to pay shipping prices on eBay so you're looking for an alternative method of getting one?
Rick Deckard · 2019-05-10 17:52
check local thrift shops or sites like craigslist and gumtree.
Switch · 2019-05-10 17:56
I have one so big it took three people to move it and I have no use for it. Come get it and it's yours. Hell... I'll pay you a removal fee.

>>16925 if you go on OfferUp and search TV and then filter by free ones, there's tons of people trying to get rid of them as long as you live near-ish to a city.

Honestly your best bet may be to look around dumpsters, especially around lower income apartments. I see them fairly regularly. Also estate sales, they may assume the TV is garbage and not have a tag on it, but most places would probably be glad to have someone take it away.

You need to network in your area, I got a consumer sony for free because the previous renter left it. I can get a few from my gf's grandmother, but why bother when I already got a trinitron.

You can find crt tv's everywhere, but if you want to use an RGB modded console you want either a pvm like the sony trinitron. But you stated you just needed something for basic gaming so a craigslist tv would be fine. I actually have several just cluttering up my attic. I want to rgb mod one of them and have already located the schematic. Turns out they used to print the schematics right in the owners manual. Oh what a time for technology.

I'm a CRT freak. I collect them compulsively. I've found several on the side of the road in the past few months, including a gigantic CRT rear projection television--that's a three-for-one--it's got red, green, and blue oil-cooled overdriven tubes in which the oil reservoir is also the optics for projecting the image. It's pretty clever. It all works--you can drive the tubes independently by feeding black-and-white images into each channel of the component input. Also have some oddballs, like a side-firing CRT for a Sony Watchman and a tube with a screen only a centimeter across--it's the smallest CRT viewfinder I've found thus far. Its pixel density is bonkers, way better than any LED display has even today. Got a few green phosphor tubes for old terminal monitors, plus some CRT oscilloscopes. Got some round radar-display style screens. Oldest one is from the fifties, so all its electronics are also based on vacuum tubes, including the display of course. It can be made to display an image by synchronizing the sweep and using a Z-input. Found some at the thrift store. I really haven't spent much on all of 'em. Assholes on Ebay are selling them for retro gaming. Charging a bundle for them. It's ridiculous. Sometimes you can get some good hits by using -retro -gaming in the search field to cull the dinguses trying to cram every SEO term possible into an overpriced old turd. You say you want one for gaming--It's understandable. Artwork for games was once all designed very specifically with the image artifacts CRTs create in mind. The look is radically different. Some pretty impressive shading is done taking advantage of the way a shadow mask distorts the image, almost like sub-pixel imagery. I've heard there's plenty on facebook marketplace / craigslist / some other similar website I can't remember the name of. I don't mess with facebook one bit so I wouldn't know about that. Unless you get a CRT from the era of the great capacitor plague (look it up, it was a thing) don't listen to the ninnies telling you to replace every capacitor in an old set. Destructive capacitor failures that aren't from those already known to have manufacturing defects from the start (and most of those are already blown) are extremely rare, even after 40+ years of sitting in an attic. But people are paranoid and neurotic and it's become a bit of a fashion trend to re-cap all your old electronics. Bah, humbug I say.

>>17709 I'm trying to collect rare CRTs too but I'm only looking on ebay since i don't really have any thrift-stores is my area and i don't want to join facebook. I have found some cute really small ones and i want to get them and figure out how to drive them but i always postpone it for more important and rarer purchases. I've only saved a few near trashcans because i can't imagine them getting crushed and used for their core metirials and also i can practice driving tubes before i get the rarer ones

>>18438 I've only got three without the original working driver circuitry and flyback transformer and such. Most of that circuitry is pretty dang sturdy; if the tube is intact, likelihood is the driver circuits are more often than not also intact. If you don't wanna get too deep into custom analog circuitry to get video into them, you can always get a cheapo hdmi-composite video converter box on ebay, or an RF modulator if it's an old antenna-only TV. The RF modulators I've gotten online for like fifteen bucks max have been so leaky that I haven't even had to connect them to the antenna in or find an input pin on the board to get video on the tube; it just kind of jumps a few feet through the air and the picture is just there. If you wanna do some fun vector stuff, you can always experiment first by disconnecting the horizontal and vertical deflection coils and just like hooking them up to an audio amplifier. Real easy to make a crummy, quick-n-dirty audio oscilloscope just by leaving say the vertical deflection hooked up normally (where it will basically be a 30hz refresh on the vertical) and hook up the horizontal to the speaker wire terminals on an amplifier of any kind. Turn down the volume all the way and slowly turn it up to find the right amplitude. Then you can make more complex vector driving with an actual microcontroller (or go full-analog if you're into it). But anyway, yeah--usually it's pretty easy to drive them. https://www.ebay.com/itm/Vintage-Sears-Solid-State-Portable-Go-Anywhere-TV-AM-FM-Radio-Model-564-WORKS/223255336796 Anything like this. Probably can find something even cheaper. I like this model, though. I already got one lying around. It doesn't have an aux input though, so you'd have to use an RF modulator to basically make your own little analog television station.
Yuki Nagato · 2019-08-05 22:10
>>18447 Oh and forgot to mention--Raspberry Pis still for whatever reason have native composite output, so you can use one of those real easily to either drive a composite set directly or drive an RF modulator without having an HDMI-composite converter as a middle man.
Otto Normalverbraucher · 2019-08-06 02:35
>>18448 Well, i really want to make my own driving circuit, high voltage supply and everything, the problem is time. I have some projects that are gonna take forever to finish and I got some vacuum tubes to learn and play around with in the mean time. ( i got them in an auction where the price was the shipping cost :P about 50 of them i don't remember and i'm not at my lab atm) I think a few pentodes and triodes Also for me shipping is quite expensive generally especially from the US, for example it's 120$ for the tv you linked :/ Anyway thanks
kiwami · 2019-08-08 15:16
TV shops. I can get one for 30 TL or 5$
Kiwami · 2019-08-08 15:18
>>18447 Hey I have one that looks like the one on your pic. It's made by National and it has German decals.
Nanashi No Gombe · 2019-08-08 17:08
>>18525 Where is this TV shop? Haven't seen a glass teat in one for ten years, but I'd love to visit this place
