I have a problem with playing 12 'vinyls at 45 rpm I bought two albums, one 200 g, second 180 g. Both with a playback speed of 45 rpm. Beogram 5000 recognizes them as 33 rpm and I manually switch to 45 rpm.

Unfortunately, the sound is much worse than at 33 It seems that the needle leaps between the grooves. Where is the problem ?? With MMC4 after the retip ?? Maybe I have to try once again to balance arm ??

 

Help me, my B&O all-knowing colleagues !!!

I lfted the top cover yesterday:

 

 

According to the manual, I made all adjustments. I set:

- turntable height

- pick-up height

- pick-up arm paralleism

- adjusting the lever from antiskating while the turntable is working (the tension and loosening of the arm almost has no effect)

 

I talked with Joseph about this problem and he decided that exchange my retip MMC4 to another (MMC4 with nude diamond like in MMC3)

You see right on photo but transport screws now are loosen . I attached it when I turned the turntable to disassemble. I loosened it when I did regulations too. 

My MMC4 is about 15 hours after retip. Retip did Joseph Long aka "Needlestain" from US.

I dont know Joseph. but I have done various retips (MMC2-4, SP14 with "Schalplattennadeln" (Axel) in Germany, and bought a SMMC4 from Soundsmith  so maybe you have something with your MMC4, lets see when you get another one

Next week I get my Beogram 5500. I will put there this MMC4 to try on linear turntable. After that, regardless of the result, I am sending MMC to exchange.

and maybe faster I buy another one MMC ( I try buy MMC2 )

The problem with MMC solved. I sent the cartridge to Joseph, he immediately sent me a new one. Now it sounds perfect on every vinyl There are no problems either with shipping or with exchange. I just recommend retipper, first class !!!!
