Established in 1946 as the Kasuga Radio Co. Ltd. in Komagane City, Nagano Prefecture, Japan, in 1960 the company was renamed Trio Corporation. In 1963 the first overseas office was founded in Los Angeles, California, USA.
In the early 1960s, Trio’s products were rebranded by the Lafayette Radio Company, with a focus on citizens’ band radio.
An importer of Japanese-made electronics RadioShack was A&A Trading Co., and a bilingual Japanese-speaking manager from there, William “Bill” Kasuga partnered with George Aratani and Yoichi Nakase to establish a company that would be the exclusive importer of Trio products.
The name Kenwood was invented by Kasuga as being the combination of “Ken”, a name common to Japan and America that had been tested and proven acceptable to American consumers in the name of Kenmore appliances, and “Wood”, referring to the durable substance as well as suggesting a relation to Hollywood, California. The brand recognition of Kenwood eventually surpassed that of Trio’s, and in 1986 Trio bought Kenwood and renamed itself Kenwood. George Aratani was the first chairman of Kenwood USA Corporation and succeeded by Kasuga. Kenwood merged with JVC in 2008 as JVC Kenwood.
1 - Electrolytic capacitors are among the most important in an audio equipment and replacing them with high-quality capacitors from the factory will improve the sound quality
2 - Electrolytic capacitors have life of work 1000-2000h then begin to lose their qualities
3 - The use of Audio-Grade Capacitor Nichicon / Elna which are made specifically for audio equipment from high-end will make your machine in good times higher
What is audio grade capacitor?
This is capacitors specifically for audio applications. These are designed to give premium sound quality when compared to general purpose capacitors. Nichicon's MUSE series and Elna SILMIC II, ideally suited for first class audio equipment where qualitative and quantitative characteristics are required.
What you should know when you make replacement
1 Mark all cables when separate circuit boards to avoid confusion in the assembly
2 All capacitors meet on parameters of old, replace them one by one so as not to get confused!
