Re: Any experience with CDM - 4/33 pickup?

Graham, Martin:

Thank you for your replies.

I corresponded with Tim Jarman over at Beocentral; they are indeed resistor fuses.

Any ideas where they can be purchased? I'm having a hard time finding that exact value.

Tim suggested finding a dead pickup and salvaging the resistors from there. Does anyone have a dead CDM 4/33?

Thanks,

Derek

Sounds like resistors used as fuses.

These components are associated with the 5v supply. I have never seen a fault of this kind in this area so cannot be of much help.

I suggest you contact Tim Jarman at www.beocentral.com who will at least understand the circuit and may be able to fix it for you.

Hi:

I was given a non-functioning CDM - 4/33 pickup that I'd like to fix. Does anybody have experience repairing these units? It came out of a BC 9500.

From visual inspection resistors 3107 and 3108 are burned. The service manual states that these are to be replaced with identical components. 4.7 ohm 2% 1/3 resistors. Does anybody know what these resistors do and what is so special about them? Would 4.7 ohm 1% of a quarter watt work also?

Thanks,

Derek
