Hi, I have a Tektronix 2225 with a broken CRT and, apart from getting the exact replacement for it (already asked in the Buy/Sell/Wanted section), I was wondering what other scope model might be using a compatible tube. I have a 2235 scope and I was initially thinking of using the CRT in it, but then realized that tube has the connections to the deflection plates on its side, whereas the tube in the 2225 has all its connections on the neck connector at the back. Does anyone know of any other scope with a CRT like the one in the 2225? |

AFAIK, the CRT for the 2225 is unique to that scope and its relatively rare derivatives (see the Tekwiki page). The p/n is 154-0907-00 and I believe QService shows one available. IDK if a more common CRT might be made to work by rewiring the deflection grid circuits. Is your 2235 functional? If not, perhaps it would be better to repair that scope? |

Based on search results, it appears the Tektronix 2211 is another scope model using the same CRT. I did see the tube on QService's site, but the cost would be over EUR 130. :) --- Quote from: bdunham7 on November 09, 2024, 05:08:59 pm ---IDK if a more common CRT might be made to work by rewiring the deflection grid circuits. --- End quote --- This is what I am looking for. --- Quote from: bdunham7 on November 09, 2024, 05:08:59 pm ---Is your 2235 functional?

2225 should be a common scope in europe, how much is a replacement or parts scope compared to the tube? Jeff |

I couldn't find any for parts 2225 up for sale (or recently sold) on the bay, but working ones seem to go for over GBP 100. |
