Stereo cartrdge now playing mono!!


My Hana SL (after a move to a new house only gives me mono! I have double checked the phono equalizer and connecting pins. At present I am just listening off the phono equalizer which reproduces normal stereo with another source.Any ideas?

@lewm , isn't that something. I can't count the number of times I did something thinking it sounded better only to realize it did not. Expectation bias?

OP, you need to try another cartridge. If it works fine the Hana has shorted out. Please check the cartridge pins again. Are the Hana's color coded. Make absolutely sure beyond a shadow of doubt that you have it hooked up correctly. If the Hana's pins are not color coded it is very easy to make a mistake. 

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.

this is kinda perplexing since I cannot think of a failure mode that would turn a stereo cartridge into a mono one.  

The fact that you reversed the phase of the right channel (swapping red and green) suggests to me that you were mischaracterizing the sound of one channel with inverted phase as mono but this doesn't explain why the hum would suddenly show up.

glad to hear the new cart is singing.... Enjoy!

As A.J. explains, many times it is due to the very fine wire from the magnet assembly/transducer to the pins sustaining fatigue-failure. The very fine wire is often not long enough and becomes brittle with use. When it fails there is no repair. The manufacturer just replaces it. At a price.
