1U version in this footprint is just not possible, it can be done with other bobbins and lams, but everything would be different!
Few more pictures of finished first batch!

Hey Spence, Those look great! Will those fit in a Neve  1073/1084 frames? I'm working on a rack of clones and stumbled across this thread . I've never been happy with the Carnhills as compared to the originals but in no way do I have the knowledge to be able to recreate the trannies. Would you consider making them for some of us DIY'ers?

Vintage  LO1166 transformers fit into the single space 500 format just fine. I keep reading that they will not, but they do. Trimming the fiberboard a bit is all it takes. Doesn't need any kind of mod to anything other than that. Accurate repros probably should fit too, but it is said again and again a compromise is necessary on repros to make them fit. But if the real vintage LO1166s fit...

Where did you get that TO-3 heatsink?  Looks great!

All the available versions use M6 lams, just different thicknesses and sizes, these are to original spec as supplied by CJ who reverse engineered a good few of the originals. Everything spec wise is right on the money and checks out.
I have Carnhills in one of my Neve's and it sounds ok, but these just blow them away, so much better.

Hi team, does anyone know if there's a difference between the LO 1166 and the LO 1166 /A...... I can see its been wired in parallel winding configuration both on the primary and secondary..... thanks
