Refreshment maintenance has been completed, such as replacing 4 electrolytic capacitors and 6 oil capacitors! The famous MC240 has a velvet transformer. The luster and freshness of the mid to high range has an appeal that is a bit different from the MC275. The exterior has been re-plated and re-lettered and is dull, scratched, and lightly rusted. *The dials for each GAIN are different from the original (Hitoshi Kobayashi)
