Besides the 17BP4 is 70 degrees deflection, pretty sure the 23BP4 is 110 degrees. For starters you could use a 8YP4 test CRT.
[edit] just remembered, I think you'd need a socket adapter when using the 8YP4 universal 110 degree test CRT. Last edited by Kevin Kuehn; 06-02-2013 at 12:39 PM. |

Silly question (I think)...but would the electrolytics still go bad in an unbuilt kit?
I had heard it was time as well as operation that dries up electrolytics. I've heard of so many TVs that were fine the last time they ran, and then were stored for so many years, and then had all the various vertical, horizontal problems that come with bad caps.

Not a silly question at all.
An electrolytic will degrade if left unused, but can be brought back by "re-forming" it - slowly increasing voltage across the cap until the specified working voltage is reached. A decades-old electrolytic has a good chance of being dried out, whether it was used or not. Re-forming won't bring those back. If I were to find an old kit and build it, I doubt I'd use any electrolytics or paper caps in it. |

Well it's not put together yet; I 'm looking at a temporary
Fix until the correct CRT 23BP4...can be located and purchased Preferably a NIB,NOS CRT see if ya'll can find me one!....Jody |

47'Plymouth would be smart to test them all before building the kit. May save a lot of grief later.

Yes,I'll install new type caps and not use NOS ones...

I have 5AXP4,a Selson test tube setup; I 'm looking at a temporary
Fix until the correct CRT 23BP4...can be located and purchased Preferably a NIB,NOS CRT,can ya'll see if you can find me one....with a 110*degree Adapter ...that would be a temp fix until a 23BP4 is located! Last edited by 47'Plymouth; 06-05-2013 at 08:13 PM. |

Being it's a series heater string, be cautious that whatever CRT you use has the same heater current draw as the 23BP4.

I want to thank you for the assistance and to Winsco Jim for the schematic
It's been a big help...Dennis told me;the manual did'nt include a schematic But everything else is in the kit!...Jody |

Dennis,sent a text that he got his money for the kit today.,
and send it out quick ASAP...I'll have pics of it soon laid out,and build soon |

Got a 23ANP4 and wire up maybe differently I wait until have the
kit 1st; it will be here Wednesday will have pictures posted ASAP anyone have a diagram of the 23ANP4??..I got a 6.3 vac filament transformer For a separate power supply for the CRT Need to fiqure out the rest of the supply for the tubes |
