    Anyone know what type of resistor this is?

    Sir teddywinters . . . . For a final confirmation, why don' t you use my suggested procedure , and I believe that you are going to find that you can read half of the units intact resistance .

    Anyone know what type of resistor this is?

    I am figuring upon its "half resistance" as being 10 ohms. In your initial photo . . .it " Photographed" like a 2 watt unit . . . but the later measurements, comparatively being related to a ruler, reveal a smaller wattage rated unit and possibly of carbon film . . . if intended as being...

    Marshall80 . . . . . . . First of all . . . . I seem to be seeing an unuseable "photograph" that has been EA'd to assimilate the renderings of a watercolor portrait . . .? . . . . . As well as the foreground fish food container. Considering the frontal foreground fish species . . . ...

    Mic preamp repair help!

    Sir Fangsstl . . . . . Is this unit being "new" to you . . . . and thus possibly, not all of its operation, being all familiar to you ? Or is this a long time owned unit and you being as familiar with it as the back of your hand ? If the latter . . . . . do all of the " Christmas Tree " of...

    Anyone know what type of resistor this is?

    Sir Theodorewinters . . . . Put me in that 2W line also . . . . and almost entirely expecting it to be of a laser trimmed metal film composition. If you were to take an ohmmeter scaled up to read 20 ohms . Touch the probes and short them out confirm your in circuit and contact resistance...

    CD Player Won't read disc

    Sir Gstutz44 . . . . Should it be that you haven't touched the unit yet . . . do observe these precautionary CAVEATS. Get good lighting for initial observations and note the convex lens. It is being electromechanically and magnetically controlled such that it can make MICRO, and that is...

    Help with diode replacement

    Are you just grasping for straws . . . . . what is the Vf being read across it with a DVM in diode test mode . . . . with it possibly reading ~200 mv, unless you have a shorted junction.

    Yorkville 100watt Mixer/Amp - Replaced Transistors

    Clarify this . . . Would it hurt if i just swapped the BC550C backwards and tested? If you mean inverting its collector and emitter leads and powering up ? Relatively . . . . . Would it be OK to plunge an ice pick into your eye? Would it be OK to install your car battery + and - cables...

    Sony TC-WR770/870

    Sir Daryl . . . . . Referencing to the simplified schematic at the very top, first . . . . . considering that you do not have a blown R704 fusible resistor . . . . . what supply voltages do you now have ? Finding those supply points on full schematic 2. OR confirm if you have AC output...

    Yorkville 100watt Mixer/Amp - Replaced Transistors

    BC550C was replaced . . . . would anything work if it was backwards? The exact problem which you are now experiencing could be the fault of a mis installed 550 or that past short having blown its emitter junction open. Feel free to initially try all tests in circuit, but if you find a large...

    Yorkville 100watt Mixer/Amp - Replaced Transistors

    Sir Jason Geeeeeeeee . . . Your supplied numbers tell us that you definitely have problems in your biasing and drive circuitry. The unit is going into full clipping very early on with that applied audio test signal. Just as preliminary, yet using thorough testing protocol, lets test the...

    Help on resistor.

    Sir RT59 . . . . Since there's 2 resistor symbols on the board, I'm stuck whether those resistors have to be fitted or not in order to get those ports working . . . . . . Those two audio handling connections are dead unless there is a relevant mating cable that is connected to J2 connector...

    Yorkville 100watt Mixer/Amp - Replaced Transistors

    Sir Jason . . . . . .Geeeeeeeeeee . . . . . Here is your markup, it being presented as a circuit board PICK-CHOOR, as it seems you handled it better than a schematic page before. Your new replacement power transistors are marked up, as per positions, and you must already have them in the...

    Help on resistor.

    3EIPB101401KME3900 Your marked R1 and R2 relate to the mic input connector circuitry to J2 connector. With R2 relating to matching impedance, and for SS circuitry 47K and 10K are two common values. The R1 is related to input attenuation and 470 ohms or just a jumper wire equates with two...
