Magnequest has original prints for many older transformers. Part of transformer winding is an art: precise wire placement and wire tension. Most windings are tensioned by pulley with a weight attached.
Little known facts focus on even smaller differences in materials. Older trannies used paper separators, and different wire insulation. Supposedly newer material is electrically better but the sound is not necessarily the same.
In speaking to a designer who designs his own OTs, his complaint was that it took him a decade to find a winder who would follow his specs exactly.
On the other hand, modern winders abound
Dave Slagle is just one such winder. Still it takes time and experience to become tops in any field. Word was only one individual wound the OT for the Marantz 9's. Takes a lot of practice and repetition and observation with experimentation. If you don't have a large company to back you the stack of dead iron can grow quickly
