I believe the transistor for the speaker circuit just broke IMO, sitting an hour in rain would do it.

It’s really not much, 8 buttons, you push one, the lights go on, and a little melody plays. When the button is pushed, the voltage on the controller leg drops a volt or so, and the “out” leg starts showing some for lights.

The way it broke, as it’s there is no sound. You apply the 3V via a resistor which takes care of the voltage difference.

Or I don’t understand what “LVceo: C the first line, and P73C on the second line. Pawel Veselov 1 5.

C P73C Ask Question. Then the spec for 2SC says: For each, one right leg is straight to the batteries, the second left leg is to the chip through a resistorand the third one middle is to the outlet from one it’s to the speaker and from another it’s to lights. It very much looks like this: I’m sorry, this is confusing: Sign up using Email and Password.

The out leg that goes to the speaker doesn’t ever show any voltage, yet its leg that goes tgansistor the controller shows different voltage drops I assume that’s the controller “playing” music.

On the other hand, they say Vebo is 5V max Now, I really don’t know much about this, but really wanna fix that toy: Some of the answers I’ve got tell me this is 2SC, which is then, according to http: I’m trying to fix this little electronic toy.

There is a transistor or I think it is for each circuit.

Pawel – Vebo – is the reverse base voltage, negative with respect to the emitter. Nearly all transistors that are labeled according to the Japanese standard JIS lack the leading “2S”.

If so, and I were to order a replacement from, say RadioShack, how would I find one that would work? See here page one for LVceo and some other relevant terms. Email Required, but never shown. Dormant, controller leg has the same voltage that is coming from the battery, and the “out” leg has nothing on it. All right, so just to settle LVceo – 50V min.

And what’s with the P73C part? But, the only things I see on this transistor again, I don’t know what is it, reallyare: In most applications not relevant. And also, how do I tell that it would open when the base-emitter voltage drops, not when it will be applied? Trahsistor was able to replace this transistor with 2N I should’ve been more careful picking the replacement that had the same order of pins, but hey, this was the cheapest one available.
