Up for sale is an ultra rare Audiophile Products MCT-1 Silver Wired MC step-up transformer. It was specially made for cartridges between 3-5ohm, transformers and interconnect manufactured by Mr Kondo himself, so you are looking at a very early model of Kondo silver wired MC transformers with SKL-VZ interconnect. Please check pictures on the below link to identify that the transformers potted and the interconnects are the same, even the RCA plugs!http://soundgate.net/product/MTAzMA...highend Also here a description on the early Kiseki products where it directly describes that these very early transformers were made by Mr Kondo:http://kiseki-eu.com/kiseki-mc-phono-cartridges-how-it-all-started/It reads: Mr. Kondo agreed to design and produce a special transformer for Herman. The first one he got was in a kind of “cigar box”, but it worked very well. In his hotel room Herman designed a housing for this transformer and a week later he had a sample of the MCT1 Silver transformer. Anyways, the sound is just sublime, I was using it with my SPU cartridges in the past with great satisfaction. Only selling as I have 3 transformers and too many preamps. I no longer have original packaging, but item will be safely packed. Satisfaction guaranteed. I can ship Worldwide, except Russia and Ukraine, sorry!
