导读
这篇文章介绍了索尼 PVM-4300——有史以来最大的 CRT 显示器。文章回顾了这款 43 英寸专业监视器的技术特点与历史地位，并链接了相关修复视频。
为什么经久不衰：CRT 是人类曾大规模量产的精密玻璃真空管显像技术，如今已无工厂能再生产，这类记录其巅峰之作的文章对怀旧硬件爱好者有持久吸引力。

推荐配套的修复展示视频，补充更多硬件细节
别错过文末链接的 Shank Mods 视频，他能搞定这件事简直不可思议。他还做了第二个视频（未在文中链接），展示了更多实际硬件细节。

Don't sleep on that Shank Mods video linked at the end, it's insane that he managed to pull that off. He also made a second video (not linked) which shows off more of the actual hardware. https://www.youtube.com/watch?v=Dgkw3uu19V8
CRT 是量产的精密粒子加速器，如今再也无法制造，堪称奇迹
我拥有第二大的一台，还有 25 台其他 CRT 接在车库里，接模块合成器、电脑、复古游戏机和多台 DVD/VHS 播放器。但即便如此，我可能还是愿意用它们全部换一台 PVM-4300。CRT 本质上是装在玻璃真空管里的精密粒子加速器，我们曾大规模量产并放进千家万户，只为电子化重现娱乐画面——如今地球上已没有一家工厂能再制造它们。这是人类干过的最疯狂的事情之一。

I have the second largest, and 25 others, hooked up in my garage, fed by a modular synth, a pc, retro consoles, and several DVD and VHS players. Would still probably trade it all for one of these. CRTs are literally precision particle accelerators in glass vacuum tubes we mass produced and put in peoples homes just to electronically reproduce entertaining images, and there is not a factory left on earth that can make them anymore. It is some of the wildest shit humans have ever done.
CRT 清仓时代白菜价买到巨屏，但重量惊人，最终不得不丢弃
2006 年买房时，房产中介送了我们一张 2500 美元的百思买购物卡。一台全新的 720p DLP 背投电视几乎花光了额度，但还剩点钱。我注意到他们在清仓 CRT 样机，其中有一台巨大的三星（记得超过 34 英寸），标价 0.72 美元——我永远忘不了这个价格。后来搬家时 CRT 早已过时，五年没开机，我决定扔掉它，才发现它重达 250 磅以上，得叫两个朋友帮忙抬到路边，垃圾公司还得专程跑一趟。我有点后悔扔了它，但它确实是家里最重的家具之一。

Sometime in 2006 we bought a house and our realtor gave us a gift certificate for $2500 at Best Buy (weird, but...those were the days). A brand new, state of the art 720p DLP projection TV was just a hair under that - we still have it and it works great. But I had a couple dollars to burn off on the card. I happened to have noticed that they were trying to clear out any remaining floor models of CRTs. One of them was an absolutely giant Samsung, memory says it was >34", but I'm not sure how big...with a sticker on it for, and I'll never forget this...$.72. Soooo two big TVs for the price of one! Long story short, we were moving out of that house, CRT tvs were long since obsolete and that TV hadn't even been turned on for at least 5 years. So we decided to throw it away. I had never picked it up before and had forgotten how heavy CRTs could be. I ended up having to get two friends to come help me move it to the curb, it was well over 250 lbs. The trash company also complained when they had to pick it up and had to make a return trip. I kinda regret getting rid of it, but it was among the heaviest pieces of furniture in our house.
安全提醒：老 CRT 内部高压电荷可保持数周，拆解前务必放电
如果你喜欢摆弄老硬件，注意老 CRT 有个能坑到你的陷阱：它们内部会储存电荷，电击强度足以把你击倒，而且这种电荷能保持数周甚至更久。在拆弄 CRT 之前，先搜索如何给它放电。

If you like playing with old hardware, be aware that old CRTs have a gotcha that can getcha: they hold a charge that can shock you across the room, and they can hold that charge for weeks or more. Google how to discharge it before poking around in a CRT.
