hi,
spec is 5K:5K 25ma.
recently I collect some 80% supermalloy EI-66 lamination with 0.08mm thick from the remain stock of nippon steel crop. It contain two type of element ~78% nickel & 2% of cobalt.
I also order Furukawa "TEX-F" is coated with three insulation( ultra thin insulate layer) which prepare to call Daburu to OEM 5K:5K 25ma interstage transformers for tube amp.
This interstage will very good for use 6c45,417a,437a,3a/167m,5842, E180F ( triode connect) etc
5K:5K 25ma was working well of high gm tubes such as above were only a few examples. Tubes with internal plate resistances around 2,000 ohms or less will work well with this Interstage.
spec is 5K:5K 25ma.
size of the core was EI-66X40
Pls saw the spec of the new wire.
"TEX-F" is coated with three insulation layers which are of dedicated polyether sulfone (a super engineering plastic) and enhanced in high-frequency V-t performance.
Features
Temperature Index: F type (155°C)*1 under IEC 60172
Ultra-Thin Three fold Insulation (100µm)
Wide Size Choice of 0.2 to 1.0mm (diameter)
Fine High-Frequency V-t Performance
Due to the core only 38pcs.
It means only can produce 19 pair of this type IT.
I would like to try groups order for this IT.
Pls understand superalloy is very very expensive.
Hand over time will 1 month.
Furukawa wire was special order which was paralell 4 pcs of wire. in parallel form, Factory funish, not litz form to lower the loss of the HF & prevent skin effect.
Fubish look was hammer tone full enclose outlook.
Sample test in spec 26Hz~68Khz -1.5db.
Group price will USD 360 per pair.
19 pairs only because limited of the core only 38 pcs.
Postage include by EMS world wide.
Photos show the core.
thx
thomas
