Hi,
Thought I'd Document my journey for making a Neve style input transformer.
So at least I have something to refer back to once I'm done, if I want to make more.
Initially I'm just going to make two but I do need to make about 10 of them for my pre amps.
I have bought some nickel lams and bobbins EI-35 size first of all and need to look at getting the correct winds, enough inductance and low resistance.
I have my own winder and was thinking to start winding the following, if it fits on the bobbin.
PRI winding - 84 turns X 2 , SEC windings - 168 turns X 2
This should hopefully give me the step up 1:2 ratio I will need for the mic pre amp.
I'm not sure whether it needs to be gapped or not, I'm pretty sure it's not, but would be better to confirm this.
I also have some mu-metal cases I can pot them in.
If anyone could chirp in with any info on bifilar or reverse winding any of the winds needed etc this would be fantastic.
Regards
Spence.
