F-7000 SERIES
This has been developed and manufacturerd with an aim to improve a tone quality from low zone to high zone, using the permalloy core (Nickel content approx.38%, special order by Tamura), including output transformer which uses permalloy core for 3-pole tube single exclusive use, and output transformer for push-pull. The products have been completed to contribute to improve customers' sound life, carefully selecting a tone quality which is indispensable for output transformer. Having sufficient output capacity and volume of information, the customers will hopefully enjoy an excellent wide zone sound through various feelings such as voluminous low and high zones, also expansion of sound and profound vivid presentation. Entire satisfaction will be covered without feeling of an existence of the analog and digital source.

Output transformers for 3-pole tubes exclusive use, marking a constant loss 0.25dB value for first time for the output transformers. This fact was due to our attempt to have good selection of iron core, sufficient margin for output capacity, and a success to reduce the primary winding resistance to below 1/5 of the traditional level. Further, satisfactory results were obtained for the frequency, phase characteristics which were factors of inverse proportion.
