    L250 vs. 250Ti Crossovers

    Now I have a set of L250's and 250Ti's, I thought I would post some crossover photos. I have seen various photos on this forum but these will summarize them all in a single thread.

    Andy, years later, I want to thank you for posting these photos. Just this weekend from my uncle's estate I received one pair of L250Tis (I'm storing them for my cousin) and one pair of L250s (my cousins gave them to me).

    I may recap the 250s eventually. Your photos give me a start. I can see the coils are a little different on the 250s versus the Tis, but I was wondering if the caps are all the same?

    Also, do you have the schematic for the 250? I found only the one for the 250Ti.

    Thanks again!

    Also, is R1 51 or 5.1 ohms? (I think it's 5.1 but it looks like 51.) Thanks!

    OK, THAT's not embarrassing. Thanks, Jeff.

    (Although on reflection, that was about the original L250, not the 250Ti. But I have the Ti XOs out now so I can just look at it, and I'm sure the information's in one of these threads --- I lose track.)
