High Performance = Ultra Thin Special Permalloy/Multiple Laminated Core This is an exhibit of Tamuras custom-ordered transformers.TYPE-L has a high step-up ratio and is suitable for low-voltage/high-power low-impedance MC cartridges.This is a product from the time when the PASS terminal was equipped for MM cartridges, and is a so-called early model.For the fussy fanatics who use MM and MC cartridges according to their music sources and moods, this is a good choice. For enthusiastsIt is a very nice feature to be able to use the PASS jacks by changing the terminals.This can be done by installing a switch or something similar, but we dare not adopt such a switch.I believe that the reason why the user is required to change the cable connection is because the sound quality is the highest priority.The structure of a transformer is simple, so the material and structure of the core, its shape and size, the thickness of the windings, and the number of windings and windings are all important. The thickness of the winding wire, the number of turns, and the winding method, etc.The accumulation of detailed know-how is necessary, and experience is the key to success. UESUGI UESUGI Research Institute MC Step-up Transformer MODEL/U-BROS-5 TYPE-LHigh performance core = ultra-thin special Permalloy/multi-layer core This is an exhibit of Tamuras special-order specification.TYPE-L has a high step-up ratio and is suitable for low-voltage, low-impedance MC cartridges.The structure of a transformer is simple, so the material, structure, shape, and size of the core are important. The core material, structure, shape, and size, as well as the thickness, number of turns, and winding method of the windings, all require a great deal of detailedThe accumulation of detailed know-how is necessary, and experience is the key to success.Uesugi Laboratory has developed and released a step-up transformer for MC cartridges to bring out all the charm of MC cartridges.Uesugi Laboratory and Tamura Corporation, a renowned manufacturer with deep knowledge and experience in transformer production, collaborated to develop a transformer with custom specifications.The core material of the transformer is ultra-thin special/multi-layered Super Permalloy, which has excellent characteristics.Permalloy is a soft magnetic alloy composed of nickel and iron, which has very high permeability and is easy to conduct magnetism.It is an ideal material for transformer cores, and has maintained an unshakeable position as a core for high-end/high-performance transformers in particular.Permalloy is classified according to its nickel content, and the highest grade, 78% Super Permalloy, is very expensive.The peak of the high frequency range is driven down to the band above 100kHz to suppress the coloration of the transformer itself. In order to prevent deterioration of the separation characteristics, left and right completely independent structures are adopted, and not only the signal system including the transformer but also the grounding system is designed to be completely independent on both sides.The grounding system is also designed to be completely independent on the left and right sides.In addition, the chassis earth of the main unit is grounded from the control amplifier itself.To prevent induced hum, the chassis is constructed of special grade iron material, and the transformer is shielded with multiple shields.In addition, the transformer is floating inside a large copper-plated iron case.In order to suppress magnetic distortion caused by the steel material, our original know-how is incorporated in the signal line routing.In order to eliminate the sound quality degradation caused by the impedance switching switch, the impedance switches are dedicated to the respective impedances, and the impedance switches are designed to be used for both low and high impedance types.Two types of variations, low impedance type and high impedance type, were available.The L type has a primary impedance of 3 ?, and the H type has a primary impedance of 40 ?.The L type is suitable for MC cartridges with low impedance design of the Ortofon series.The L type is also suitable for high-impedance design MC cartridges such as Dennion, etc. and mid-impedance design MC cartridges such as Audio-Technica, etc.H type is suitable for mid-impedance type such as Audio-Technica.Both types are designed with a high margin, so the L type is suitable for 3 to 10 ohm cartridges and the H type is suitable for 10 to 40 ohm cartridges.The H type is a good match for cartridges of 10 to 40 ohms.Type MC Step-up TransformerPrimary impedance L type: 3?H type: 40?Secondary impedance L type: 2k?H type: 4k?Step-up ratio L type: 25.8 timesH type: 10 timesSecondary side suitable load range 30k? to 100k?Channel balance within 0.3dBFrequency response 10Hz to 130kHz +1.0 -0.5dBDimensions Width 174 x Height 125 x Depth 121mmWeight Approx. 2.5kgInput/output terminals on the rear panel. The upper group of terminals is PASS (through) and does not go through a transformer. (MM only).Therefore, when using it as an MC step-up transformer, please connect it to the lower group of terminals.The upper pass terminals and the lower step-up terminals are connected to each other on the inside of the four terminals.The outer terminals are outputs (L/Rch). This model has multiple GRD terminals.We have been advised that it would be more desirable to connect one terminal to the ground terminal on the amplifier side, while the other terminal should be connected to the ground terminal on the tone arm side.I was advised that it is more desirable to connect the other one to the ground terminal on the amplifier side.In fact, in our environment, we have had good results by connecting the ground cable in such a way.If you are willing to use a ground cable made with materials at hand, we will provide you with a ground cable of our own making with Y-lugs on both ends.Payment ONLY ebay Payments Please Note...
