The preamplifier which reproduced faithfully Model7 which is an excellent article of former years of a Marantz.
In order to reproduce the excellent article of former years, the workshop of a North Carolina is taking charge of a production by the operation of marantz USA Inc. in a Chicago.
The part which must be changed by transition of component partses which cannot be obtained, such as an oil tubular capacitor and a selenium rectifier, or a safety standard side selects the component partses which may be obtained, and the component partses which can be restored are newly raised and are brought close originally, such as keeping an original structure, how to construct, and the product-line way.
The power cable serves as a inlet type and the power transformer is presupposing the changed part at the circumference of AC primary that a thermal fuse is entered using the safety standard qualification article of each country.
The Valves employed is selecting carefully and using GE and Golden Dragon.
The wood case serves as an option.
