Re: Cheap Chinese cartridges
These cheap Chinese cartridges will be no good for the Dansette "Major". At best, it may only give a very weak output.

' I have recently fitted a NOS Ronette cartridge to a Garrard RC80 deck. It didn't come with a pinout so I connected the two uppermost pins together and similarly with the lower ones. When I tried it on a 78 all I got were the crackles with only a very quiet signal underneath. It turns out that the correct pinout has the pins reversed and so I had connected it out of phase. A very odd effect when out of phase.

Re: Cheap Chinese cartridges
I connected the 2 top and the 2 bottom pins and the output went up and sounds fine.
So there is no standard for the pin outs? |

Re: Cheap Chinese cartridges
Whereas 30 years ago all this stuff was second nature, there now seems a whole new mass of confusion about record player cartridges which constitutes a growing proportion of this Site's audio equipment Posts.
Whether mono or stereo, how to connect them, what output type, where to source them, what stylus, how do they track... Yet most of our Stickys already cover all of these issues. How can we better signpost?

Re: Cheap Chinese cartridges
Apart from the typo Edward, I doubt that you can Nobody wants to absorb the info over time anymore or even has the time [so it seems]. It's a combination of instant gratification, fashion and follow the money. I could be wrong of course but there is a conspicuous lack of comment from the other side of the debate.

Re: Cheap Chinese cartridges
That's what I did originally and I think it is usually the case but on the Ronette the +ve pins are diagonally opposite which is what caused the confusion. They are also just numbered 1-4. I suppose that getting it out of phase will just produce a "difference" signal hence I just got the crackles on a 78.
