In the micro-cap simulator there are many high frequency spurious oscillations that I had to suppress with a addition snubbers, otherwise the simulator aborts. I do not have a working model of the same wattage here in the mountains again. Dec 14, 3.

2SC1061 – 2SC1061 NPN Power Transistor

Also, on your working unit that has the similar inverter and wattage lamp, what is the AC voltage across the lamp when operating? I believe the values of the components would change slightly for higher wattage units. D That’s it besides the transistor.

If you don’t pay attention and follow that PCB mistake then you’ll be starting your repairs again from the beginning. The two red wires go the pins at one end of the tube and the blues transistir the pins at the other.

I’m creating a micro-Cap simulation scehmatic. Sorry I can’t help with more. Dec 20, 9.

A voltage or current applied to one pair of the transistor’s terminals changes the current flowing through another pair of terminals. In a properly designed circuit this should not happen; it should go to the landfill still working!

In the tramsistor PDF all the components are guesses, if you can determine two red colored capacitors’ values, that would be a great help too! All being set-up, double checked all the connections and passive components that appears to be fine, I fire it up and surprise, the two Ohms resistors from both channels R and R rounded with red in transistorr picture were burned along with all the drivers and final transistors.


Apart from the fact you need to twist all ‘base’ connections ttansistor any replacement transistors so that they sit in the middle – EBC or CBE as opposed to the usual ECB or BCE, the furthest right of the 4 driver transistors looking towards the rear of the unit is marked the wrong way around.

The maunfacture has private labeled all of the parts to their own code. fransistor

I plan to visit the boat later in the week again, and can bring a single tube working model up for these measurements. These may all be extraneous now, with the circuit from the patent.

CMOS Technology file 1. It would be helpful to know the package size, otherwise you run the risk of incorrect pin configuration of the transistor. Part and Inventory Search.

I’d be interested transistod your program can suggest an NPN transistor by number. Digital multimeter appears to have measured voltages lower than expected. Collector – Emitter Voltage Vceo. Then photo the bottom again and post it here.

Good replacement for 2Sc1061?

It is composed of semiconductor dataseet with at least three terminals for connection to an external circuit. I want to solve the initial design problem that causes the failure of most of the units, as you described initially: If the lamp failed to start then it’s most likley a over voltage on the transistor’s collector-to-emitter voltage during the high flyback voltage during resonance mode start up.

I have units of 8 watts, 16 watts, and 30 watts. First for your information, the T transistor is mounted on the solder side of teansistor PCB, if you wipe off the thermal grease there is a chance the true component number is hidden under the grease. The unit I have been photographing is for one 15 watt tube, whereas the one in the patent is for two 8 watt tubes, but essentially the same. Then I could do the other tests The tuner works perfectly, but I have one problem or more with the amplifier.


For a better experience, please enable JavaScript in your browser before proceeding. Anyway, here are the photos.

Transistor for Flourescent Ballast

I’ve got the circuit completed now. The time now is OK, here’s the schematic of the left channel output stage with R circled in red. From what I’ve reversed so far, it looks nearly identical once the second lamp and it’s associated circuits are logically removed. The CB only has eight parts! Any other components seemed transistlr be fine. Click here to register now. Ask a Question Want to reply to this thread or ask your own question?

Once we get all of the parts and connections entered we can confirm the function by simulation and determine why the inverters fail after only a few years. How do you get an MCU design to market quickly? Just type in H transistor. Dec 14, 1. Similar Threads Sony ta ax 2. Maybe this can give you a lead. What is the resistance across the lamp heater pins?

Or your local RV store. Once I have a copy of the board to hand, I can determine at least which wires in and out of the coil at the same loop! If it’s blank, then Thin-Lite datqsheet the original part number.

Measuring air gap of a magnetic core for home-wound inductors and flyback transformer 7. I hope this helps.
