TV Monitor

Schematic: http://i263.photobucket.com/albums/ii151/cameramanlink/TVMonitor-2.gif
Homemade television video monitor built from scratch. It uses a 23" magnetic-deflection black and white CRT. This is the fifth of five video display projects I've built. After building the Scope-O-Vision, I decided to build something completely different: a TV using magnetic deflection. The TV that used to reside in the cabinet was a Sears Silvertone from the mid 1960s (go to the website to read the whole story about how this project worked out). In short, I ended up recycling TV parts from the Sears and building it from the ground up using my own chassis, layout, and other parts. I bought the yoke from eBay because the previous one was destroyed and thrown away. Included in the video are a demonstration of the TV working, and photos I took while building it. I started with nothing but a cabinet, yoke-less CRT, vertical output transformer, filter capacitor, filter choke, audio output transformer, speaker, potentiometers, and horizontal output transformer (stolen from the stupid "Flyback Driver" you might have seen on my channel before).

Hi, on your web page of schematics, the audio generator circuit contains what - a light bulb, 120 v 4 watts? Or is that some other kind of component? I want to build one of these but here down under we have mostly 240 v bulbs.

[CameramanLink]

@Lmalarki Yes, it's a lightbulb. 240v should work fine too.

A nice metal-can flyback transformer- you don't see those very often.

[CameramanLink]

@douro20 The flyback and rectifier are inside the can (removable). It acts as a radiation shield for the rectifier.

Nice, your work is done, I want do something like that install input to watch DVD and Cable. u know there no more BC tv station. I have 1949 Admiral 30A16 in cherry wood nice art deco. I found in trash someone throwing away. I took it home all way 3 blocks alone (not easy to left).

[CameramanLink]

@RCAradio I think it's a shame that people would throw something like that away. That's a piece of history! I'm glad to hear you saved it.

@CameramanLink your very welcome, something like that deserves every bit of it!, and okay ill check my inbox now

[CameramanLink]

@codemsan Thank you! There actually IS a lot to it (having the right parts is most of it). Then it's just a matter of building it. I can tell you I probably won't be able to do another one of these unless I can find compatible parts again. I got VERY lucky this time! It was quite an experience. Thanks for such an awesome comment! I'll send you a message about the DVD.
