BRONZE MemberIt seems that 8d2 is fried.
I’m going to replace both of them, we’ll see.

BRONZE MemberThank you again so much for your help.
I’m going to change the 100mf cap because it looks worn out.

BRONZE MemberI finally managed to take the measurements
According to this picture
Tonearm raised, I get- 1 -> 30.7 V CC*
- 2 -> 21.7 V CC
- 9 -> 0.7 V CC
Tonearm sets down, I get- 1 -> 28.8 V CC*
- 2 -> 21.7 V CC
- 9 -> 15 V CC
I also played with TR2 and I don’t get the impression that it has any effect on the circuit.
Can I try powering the relay with an external battery when the turntable is on?Thank you for the time you are dedicating to my problem.-

BRONZE MemberOkay, thank you very much.
I’ll test all of that.

BRONZE MemberHi,
I think you’ve found the source of the problem.
The relay doesn’t click when the arm sets down.
I tested it by powering it directly and it clicks correctly, so I think there’s a power supply issue on the PCB 8 board.
Any idea what I should test?
Thanks

BRONZE MemberHi
Thanks for your replies.
I tested it with the 2402 cartridge.
I also tested the relay and can hear it clicking.
However, I didn’t notice if it clicks when the tonearm sets down.
I’ll test it tomorrow and let you know.
Thanks

BRONZE MemberPour ceux que ça intéresse, j’ai changé la lampe et celà n’a pas résolu le problème…
Guillaume Gonzalez
BRONZE MemberBonsoir et merci pour vos retours
Sur ma platine pas de pré ampli mais comme la BG 2402 fonctionne normalement avec l’ampli, je ne pense que le soucis vienne de ça.
J’ai également testé la continuité du câble et il a l’air bon, j’ai également essayé une autre cartouche
Je n’ai pas de connaissances poussées, mais comme il s’agit d’un son acoustique et après les heures passées sur les forums, j’ai le sentiment que le soucis viendrais du “muting circuit”.
D’ailleurs en refaisant le tour cet après-midi, je me suis rendu compte que la lampe de suivi située au pied du chariot est grillée.
Celà pourrait-il mettre la platine en mute
Merci beaucoup pour le temps que vous m’accordez
