The first time that I installed the Hana I had to reverse the pins of one channel. they pins are are colour coded. So I can only assume that the problem came with the new cartridge which is rather unfortunate,
Meanwhile I have mounted my old (number 52272) Koetsu black which I had serviced by Vd Hul years back.I wonder what it is worth.
Thank you for the responses. i will post the outcome of the Hana ituation when I recieve it.
