Use the one that produces the higher output voltage for a given set of input conditions (drive and pulse rate/width). Many variations on this basic circuit are certainly possible. Bug Zapper 1 You know the type — a purplish light with an occasional (or constant) Zap! Один его конец на “корпусе” – так относительно противоположного. Therefore, you may need to sacrifice two of these — one so that just the ferrite core can be salvaged by soaking the transformer in some nasty solvent (maybe lacquer thinner will work) to dissolve the adhesive. Use a 9,600 mcd yellow LED for LED1, and a high efficiency red LED for LED2 to get maximum sensitivity. При осмотре внутри, вижу: шток, который подтягивает ленту к звуковой головке, практически, не двигается, нужно большое усилие для того чтобы его подвинуть. В месте соединения этого штока за годы работы насыпалось много пыли, что эта пыль не дает нормально работать механике.


The cable carried bi-directional audio, video, synchronisation, record on/off control, and power. There are some of the flybacks that does so, but during this period of operation the peaks of output voltage are even higher. The time constant (R1+R2)*C1 controls the charge (high) time.

Please contact me via the Sci.Electronics.Repair FAQ Email Links Page if you know for sure from which model camera this originated.) Using the larger transformer should result in a faster charging speed. The ignition winding consists of a couple dozen or so turns of 24AWG magnet wire wound over the top of the main winding. R108A, R108B and R1 are carbon composition types, 2W resistors are flameproof, the rest are standard 1/4W carbon film. IC1 is a UC3842 current-mode PWM controller. Don’t forget that the pinout for the 79xx and other negative voltage regulators is NOT the same as for the positive variety.

Возможно допишу когда нибудь RTP классы для звука. (так как увлекаюсь до сих пор SIP)Ну и самое вкусное.
