There are some circuits with h on Google. I believe, contrary to Thinlite’s rep’s reply that the transistors are probably the culprits eg: What is the function of TR1 in this circuit 3.
Apart from the fact you need to twist all ‘base’ connections of 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. On the PCB, I need to see the solder side more clearly, rosin is blocking a few places such that I can not be sure if there is a connection or a open area.
The first photo above where you mention RF suppression, yes and more. 2zc1061
Once you have determine the type then selection dattasheet substitute becomes easier. My guess is adding the snubber that your one unit already has!

Backlighting worked really well. It would be helpful to know the package size, otherwise you run the risk of incorrect pin configuration of the transistor.
In the attached PDF all the components are guesses, if you can determine two red colored capacitors’ values, that would be a great help too! It’s a few years after the fact but I can tell you exactly why the amp started smoking after Teodore Emanuel’s diligent repair efforts What is the value of the snubber capacitor? One last item, if you have a amp meter, when the inverter is operating, what is the supply current to the inverter black wire and the supply voltage?
Between the two blue wires at the lamp socket K 3. Replacement Transformer Started by ncag Today at 7: From what I’ve reversed so far, it looks nearly identical once the second lamp and it’s associated circuits are logically removed. Search Forums Recent Posts.
If we mean resistance across the pins of the lamp itself, when not connected to the circuit, it is between 20 and 30 ohms. There are several unloaded components on the PCB and most likely this schematic is the full monty. As built, the inverter circuit doesn’t work very well CMOS Technology file 1.
Please use some hot water, soap and a brush to remove the rosin. 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.

In the real world the transistor aborted too! As above, I will bring a working unit for this measurement later in the week.

It’s clear that it shouldn’t be possible for any significant voltage to appear across it, because it’s connected across the base-emitter junction of Q Thanks for your help and advice, Kip Hansen. As for the one 15 watt tube PCB we have been looking at, as you requested, here transistir photos with the clear sealant and rosen removed.
I think it is transishor fine: The supply voltage comes from the battery bank on the boat, and is ranges from 11 volts batteries very low to almost 14 volts chargers powered by shore line, wind generator, or onboard gen set going full blast.
I have another spare pair of TIP41A transistors, but only a single pair for a single channel, so can I just leave the other channel with transistors out? Dec 14, 3. A small current entering the base is amplified to produce a large collector and emitter current.
I believe the values of the components would change slightly for higher datssheet units. Sorry I can’t help with more.
Forums New posts Search forums. In a properly designed circuit this should not happen; it should go to the landfill still working! I’m busy for a few days so it will be the weekend before I can continue on this. After that, you can post your question and our members will help you out. With a Vceo rating of at least datwsheet and a Veb rating of at least 5V.
