    Hi,

    I'm looking for someone of (more or less) Chris Merren's level to have as an alternative since he is very busy at times and orders can take forever to complete.
    Reason I need a custom OT is because it has to be ultralinear and none of the major manufacturers build a 100W Marshall-style transformer with screen taps.
    (Correction: Hammond does a generic 100W ultra-linear OT that I will use if I can't find a qualified builder.)

    Thanks!

    Ultra linear does have an advantage less distortion with cooler bias.

    No luck with those two companies. I was thinking more along the lines of an individual with good knowledge winding handmade transformers at home who could custom build to my specs...
    Thanks anyway!

    What about building it yourself. Not that hard. You need a turn counter ($5 from China) and a turn jig: i used a children's bike, modifying krank etc.

    You can buy transformer sheet metal pretty cheap. There's lots of different kits out there, with love from both Russia and China

    Why the hell would you want an ultra-linear xformer? Ever played any of the early 80's Fender amps?
    Hahaha. Just saying of course.

    Well on 1 hand it make sense because ultra-linear is more efficient, produces less heat and lower distortion.
    The tubes run cooler, and the bias does not need to be as hot.

    On the other hand, experimenting / inexperience may just burn the whole thing up...

    So a normal transformer with screen resistors makes a lot more sense, compared to custom making an U linear for a guitar amp. Especially for a person who is just learning how to build.

    But once you get all the bugs out: Ultra linear "is" a great choice for several reasons.

    Sorry for the late follow up. The reason I need a good ultralinear transformer is because I build a "Blackmore" amp that's based on the 200w Major. It's a big part of its unique sound.

    I liked the suggestion of getting the tools to make it myself!
