Datong AD370 Toroid Windings

[larley]

Does somebody know how many windings there are around the individual toroids and how they are wound?
Thanks in advance!

There are some photos in the archives showing the AD370 boards (which are the same as the AD270). Most of the transformers appear to be bifilar wound. I've never seen a BOM showing what they are though.

Do you have one that you're trying to repair or are you trying to create one from scratch?

The Bifilar wire is still available - can’t remember the gauge, however, sorry. If you can find someone with a working unit it would be a relatively simple job to remove the part and count the turns and measure the gauge - As they are wound using two coloured enamelled bifilar wire then easy to replace!

Just checked my document stash - the only document showing stock parts (and then only high level assemblies) I still have, is for the FL3. Think the rest have been misplaced or lost through the passage of time :o(
