Without transformers to measure I could not easily answer, so I consulted Per Lundahl. Here is his answer:
primary inductance of about 65H
(Inductance is inversely proportional to DC current gapping.LL1667/25mA would have a inductance of about 160H>
Possibly a significant difference depending on what you are doing.

Sorry, but I got back to this kind answer of yours and I had a flash...
Was 65H referred to 1660/20 or to 1660/25?
As a load for a 10Y (Rp 5000 Ohm ish) 65H are just almost enough, I think...Thank you a lot once more

The 65H number is for the LL1660/20mA. The 25mA version would have somewhat lower, but not drastically so, inductance.

Very helpful
1660/25 with a 65H Prim. Inductance means, with the 10Y, a Fc(-3dB) of 12Hz ish
Fear enough!
Cheers
