All 3 cores are the same (supposedly) and came from the same source.
Here is the datasheet...

hi avalon,

Thanks for attaching the datasheet for the pot core which you use.

Looks like the Permeability 2000 or 2000nm (Russian) .The mystery to solve the overunity for this circuit is getting closer and closer by the day.

I'd believe itsu is using the exact same core as i am 4.7cm AL9500 HAGY .I managed to bump into the datasheet for this old pot core which i found the material for my core is Mg-Zn.It's a grey soft core(T-1000 you were 100% right).This material won't do.

I knew it i had a weak point when buying pot core since i didn't know what to get couple of weeks back.

Вот ради этого все и выкладывалось! Новые идеи и варианты воплощения.

That's all for this and spread! New ideas and embodiments.

Hello MagPwr

"Thanks for attaching the datasheet for the pot core which you use."
spec sheet specifies this core as type 77 ferrite material.

Please see below:
Magnetic Properties   View Magnetic Properties of Ferrite Materials
31 Material   A MnZn ferrite designed specifically for EMI suppression applications from as low as 1 MHz up to 500 MHz. This material does not have the dimensional resonance limitations associated with conventional MnZn ferrite materials. Round cable EMI suppression cores, round cable snap-its, flat cable EMI suppression cores and flat cable snap-its are all available in 31 material.
33 Material   An economical MnZn ferrite designed for use in open circuit applications for frequencies up to 3.0 MHz. Rods are available in 33 material.
43 Material   This NiZn is our most popular ferrite for suppression of conducted EMI from 20 MHz to 250 MHz. This material is also used for inductive applications such as high frequency common-mode chokes. EMI suppression beads, beads on leads, SM beads, multi-aperture cores, round cable EMI suppression cores, round cable snap-its, flat cable EMI suppression cores, flat cable snap-its, miscellaneous suppression cores, bobbins, and toroids are all available in 43 material.
44 Material   A NiZn ferrite developed to combine a high suppression performance, from 30 MHz to 500 MHz, with a very high dc resistivity. SM beads, PC beads, wound beads, round cable snap-its, and connector EMI suppression plates are all available in 44 material.
46 Material   Our latest material development is a MgZn ferrite intended for suppression applications. This material does not use nickel in its composition, hence it avoids potential environmental issues as well as reduces the cost of the material component of suppression parts. The suppression performance of the 46 material is similar to our widely used 43 material. The new Fair-Rite grade 46 is supplied in the larger sizes of the round cable EMI suppression and snap-it cores.
51 Material   A NiZn ferrite developed for low loss inductive designs for frequencies up to 5.0 MHz.
52 Material   A new high frequency NiZn ferrite material, that combines a high saturation flux density and a high Curie temperature. SM beads, PC beads and a range of rod cores are available in this material.
61 Material    A high frequency NiZn ferrite developed for a range of inductive applications up to 25 MHz. This material is also used in EMI applications for suppression of noise frequencies above 200 MHz. EMI suppression beads, beads on leads, SM beads, wound beads, multi-aperture cores, round cable snap-its, rods, antenna/RFID rods, and toroids are all available in 61 material. Strong magnetic fields or excessive mechanical stresses may result in irreversible changes in permeability and losses.
67 Material   A high frequency NiZn ferrite for the design of broadband transformers, antennas and HF, high Q inductor applications up to 50 MHz. Toroids, multi-aperture cores and antenna/RFID rods are available in this material. Strong magnetic fields or excessive mechanical stresses may result in irreversible changes in permeability and losses.
68 Material   Our highest frequency NiZn ferrite intended for broadband transformers, antennas and HF high Q inductor applications up to 100 MHz. This material is only supplied to customer-specific requirements and close consultation with our application staff is suggested. Strong magnetic fields or excessive mechanical stresses may result in irreversible changes in permeability and losses.
73 Material    A MnZn ferrite, supplied only in small cores, to suppress conducted EMI frequencies below 50 MHz. EMI suppression beads, beads on leads, SM beads, and multi-aperture cores are all available in 73 material.
75 Material   A high permeability MnZn ferrite intended for a range of broadband and pulse transformer applications and common-mode inductor designs. Toroidal cores are available in 75 material.
76 Material    A MnZn ferrite with a 10K permeability and an acceptable Curie temperature for broadband and pulse transformer designs and common-mode choke applications. Toroids are available in 76 material.
77 Material   A MnZn ferrite for use in a wide range of high and low flux density inductive designs for frequencies up to 100 kHz. Pot cores, E & I cores, U cores, rods, toroids, and bobbins are all available in 77 material.
78 Material   A MnZn ferrite specifically designed for power applications for frequencies up to 200 kHz. RFID rods, toroids, and E & I cores are all available in 78 material.
79 Material   A high frequency material for power applications up to 750 kHz. This MnZn power ferrite is available in customer specific core designs.
95 Material   A low loss MnZn ferrite material for power applications up to 200 kHz with low temperature variation. New type 95 Material is a low loss power material, which features less power loss variation over temperature (25-120oC) at moderate flux densities for operation below 200 kHz. Shapes available in 95 material are Toroids, U cores, Pot Cores, RM, PQ, EFD, EP.
97 Material   A low loss MnZn ferrite material for power applications up to 400 kHz. New type 97 Material is a low loss/higher frequency power material. It features minimal power loss at 100oC at moderate flux densities for operation below 400 kHz. This material is available as special order for customer specific applications.
98 Material   A low loss MnZn ferrite material for power applications up to 200 kHz. New type 98 Material is an improved version of Fair-Rite's 78 Material, this material supplies, lower power loss at 100oC at moderate flux densities for operation below 200 kHz. Shapes available in 98 material are Toroids, U Cores, E & I Cores, Pot Cores, RM, PQ, ETD, EFD, EP, EER.

Apparently the #77 material Ferrite is ALSO a MnZn composition, NOT NiZn......

Seems the NiZn composition materials are susceptible to some type of molecular modification from Strong Magnetic Fields.

so what gives?

take care , peace
