  1. Converting CD-ROM Drive to Audio CD Player/MP3 player!!!

    in Electronic Projects Design/Ideas

    Posted

    Sir,

    First of all i express my gratitude for the interest so taken for converting CD-ROM drive into Audio player. But, I need it to convert to MP3, possibly VCD too. The problem is that can the MPEG card, which is readily available in the market be interfaced to CD-ROM's data cable output socket in order to process the same and get the things done by adding one more audio amplifier for speakers ?

    regards,

  3. Simple dB meter driver circuit.

    Dear Audioguru,

    thanks for your immediate response. You have sent me the vu meter built around (LEDs). The circuit i need is different.

    I mean to say that after the pre-amplifier out, it should be connected and the vu meter  called db meter has the needle deflection, not LEDs.

    I hope you understand by now. However, I appreciate your immediate response and guidance.

  6. Microphone Echo/delay IC datasheet.

    in Datasheet/Parts requests

    Posted

    Sir,

    While thanking you for the reply, it is very cumbersome to get the IC in India and to make a pcb. Rather, I would prefer a simple circuit or complete schematic/pcb layout/component layout with IC datasheet. So, that i can make out a pcb for that and fit it unto my mic input (tape deck) and the delay adjustable by volume control to a max of (120 or 130 us. arppx.). Does any circuit have this facility?

    I think simple transistor (cascading form) built around some R/C network will also have some echo effect.

    I appreciate your immediate feedback and also need help from you further.

    Regards,

    Sirs,

    I introduce myself as an electronic hobbyist and into the field of repair & maintenance of different branded (Sony, AIWA, Sharp, National) audio products. For this I need often the schematic diagrams of different brands to ease my sorting out problems and ease maintenance etc.

    Can anyone help me out from where can i get circuit diagrams of different models etc.

  17. Dual Volument Control (Rotate type) B50K 7-legged

    in Electronic Projects Design/Ideas

    Posted

    Hello!

    Can anyone tell me about the function of the 7th Pin of Volume Control. What does it mean?

    I understand about 3-leg rotate type volume control (Mono) and 6-leg rotate type volume control (Stereo) application, but I do find volume controls of Japan/Singapore/Malayasian origin, which has 7th leg situated back to the single line 6-legged vol. controls. I found the volument control of (B50K) like this.

    Can anyone clarify...pls do not hesitate or mind for my poor english. If not understood, i will try to convince otherwise.

    Please help!!!

    Posted

    Sir(s),

    I wholeheartedly thank you very much for the pains taken guiding me on the above. But, still I have not reached the goal.

    The Rising Radio Cassette Recorder (Made in Japan) have the ICs LA2000 (Plunger drive), M51161P for ALC & Pre-amplifier/Mic/Rec. Amp., LA4461 & LA4460 for Power Amplifier) with Detatchable speaker system.

    Regards.

  21. Datasheet M51161P

    in Datasheet/Parts requests

    Thanks for the information. My Radio/Cassette recorder is now in dead condition. I very much need the datasheet for M51161P, which may be the MIC/Equalisation/Line in/ALC  etc.

    This is used in RISING Radio Cassette Recorder (Single Deck) Metal set of Japan Make, Model #  PC 007.

    The PCB mounted (with M51161P & LA2000) unto the Deck mechanism clearly mentioning  the connection of the stereo head. So, I need to know the circuit diagram/data sheet for the same.

    Regards,
    Shamim

    hi,
    Can anyone help me out whether M51161P & M51162P 20-Pin DIP are pin compatible and identical? I am finding it very very difficult to get datasheet for M51161P, but however, I am being able to trace out datasheet for M51162P. Are they identical and can be direcctly replaced or modification in circuitry needed.

    Regards,

    hi,

    My sincere thanks for providing me the datasheet of LA2000. But, i very much need the datasheet of M51161P, which is obsolete and discontinued IC. So, IC parameters required for replacement etc. Can u pls tell me if M51162P is identical and can be directly replaced?

    Thanks you once again. I am also joining unto your website......hope to explore further , i remain.

    truly yours,

    Shamim
