A couple of LL1930 questions

K&K Audio / Lundahl Transformers

Welcome! Need support, you got it. Or share youe ideas and experiences.

I have seen the LL1930 mentioned by posters here and on other sites for use as a parafeed headphone transformer. In looking at the specs, there isn't a power handling rating. However, there is a 30dbu level rating using a 10k secondary load. From this, that seems to be 5mW of transfer. This would work well for the many 100dB+ sensitivity headphones that are out there. What kind of performance can be roughly expected if the LL1930 were tasked to handle significantly more power, say 50, 100, or 250mW?

My other question is regarding the footprint. Does the LL1930 share the same pinout dimensions as any other Lundahl transformer? I ask because it would be nice if one of the transformer footprints in the EAGLE Lundahl library that is out there would work for the LL1930.

Thanks,
