Question about a CRT.
Hi all again..
2 have a dilemmas... I have a Sylvania with a crt with no label on it, so I can't tell you the number... the other tv is a Philips with a crt ... probably universal made in Montréal but I don't know the number on the picture tube. My question is: is it dangerous if I swap the CRT from one to the other ? What is the danger ? the both picture tubes have the same size ...I want to keep my Sylvania... Brand : Sylvania Model : CL9226P Chassis : E45-1 Serial Number : 1121990 What are the substitutions for the Sylvania CRT 25' |

How old is the Phillips ? The E-45 was a delta CRT IIRC newer
jugs wont work. Remember you need it to be both electricly & physicly the same. Maybe someone has a sub book & can give you a list. 73 Zeno |

Well, without a sub book, and numbers, you can compare the two side by side.
Make yourself a pinout map of both tubes as far as what you can see from the outside. Be sure you can see the wires going to each element. Map it all out well, be sure the key points to the same spots etc. When I was in tv school me and another joker swapped picture tubes, delta's, one was longer, and the screen curve on front was not the same. It worked, but we couldn't put the back on without putting a extra bump on top of the original tube bump, good thing it was a plastic cabinet, we melted it together with soldering irons..... I think you should check out for compatible filaments too, volts and pins. If you guys didn't get to do this stuff in high school, well, you missed out big time.... Lots-a-fun!

CRT's are surprising interchangeable. As long as deflection angle, gun type, HV rating(not as much of an issue in color due to standardization), and mounting are reasonably close minor tweaking can often compensate for the rest....Sure it won't be perfectly original, but it will work.

delta gun so wont sub. Funny thing is the Sanyo tube was probably built by Sylvania, they built most the tubes for Sanyos used in the US & Canada. My E-45 manual is missing but the E-46 uses the following CRT's 25VDMP22 25VCZP22 25VDXP22 This was probably the best of the Sylvania chassii. For the uninitiated a delta gun CRT has the 3 color guns arranged in a triangle like the Greek letter delta. An in-line CRT has the 3 guns arranged in a straight line & a more modern design. 73 Zeno |

a long time since I worked on one so not sure. Did you look at the layout chart in the set ?? Sylvania had a lot of info on theres & maybe the CRT number is on it. 73 Zeno |

there is no e 46 chassis in a 25 inch set.the next in series is e 48.the crt will interchange with any 25v delta gun.i own e 45 and e 48 sets right now.the 25vdmp22 was the best looking crt ever made.didnt last long but they made the best picture.

No not yet because my Sylvania is in a basement at the house of a friend and this set is at almost 50 miles from me, When I will have the time I will tell you the other informations about it. |
