Potentiometer Questions Started by norbss Yesterday at I don’t know of anyone else with a wide range. 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.

As a first test you may try TIP flat, black whether the circuit works at all with a bipolar transistor but this type is only with V collector so may not work on the long run, but probably it is easier to obtain locally near to you? Assuming it is a bipolar transistor and not a power MOSFET you may simply substitute it with a hefty bipolar transistor for a test try.

Tanuki, This is great. The E symbol is shown on the right whereas it should be on the left. Sorry to be delayed so long, I had to repair a friend’s computer that had a bad hard drive controller.

With these values and guessing that the inverter operates around 40KHz, I can tune the transformer parameters to a reasonable guess. The extra capacitor is a snubber to limit the transformer’s primary leakage inductance fly back voltage, which reduces the high voltage stress on the transistor. Sorry Trajsistor can’t help with more.


I will try datadheet suggested transistors and see what works. Dec 14, 1. Ask a Question Want to reply to this thread or ask your own question?

Patent US is xatasheet interesting and related to other larger wattage lamps. The CB only has eight parts! Or your local RV store. Also, on your working unit that has the similiar inverter and wattage lamp, what is the AC voltage across the lamp when operating?

Base to the lamp heater and clamp diode. I hope this helps.

Good replacement for 2Sc1061?

That sneaky old unidentified Q1! Once datasheer figured out what’s wrong with the connections to Q and added the fusible resistors, you can start measuring some voltages to figure out what’s wrong.

The tuner works perfectly, but I have one problem or more with the amplifier.

You have several options: Isnt the number market below that? As built, the inverter circuit doesn’t work very well I should hear from the shop on Monday, and I’ll let you know the result. Hope that helps someone. I think it is just fine: I DO have a working copy of the board, but don’t know how to check transistor types with a multi-meter.

Dec 242: Feb 3, Synthesized tuning, Part 2: I have units of 8 watts, 16 watts, and 30 watts.

Silicon NPN Power Transistors

In a properly designed circuit this should datasheeet happen; it should go to the landfill still working! Replacement Transformer Started by ncag Today at 7: One other thing, when the lamps fail are they operating or do they fail to start. It would seem that given the function – a flourescent 12 2cs1061 ‘ballast’ – for running 2 F8T5 mini-tubes — that some smart guy ought to be able to guess what this MUST be. From what I’ve reversed so far, it looks nearly identical once the second lamp and it’s associated circuits are logically removed.


I never would daasheet thought to search the patent office for the circuit diagram. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. Apart from the fact you need to twist all ‘base’ connections of any replacement transistors so that ratasheet 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.

Also on the transformer, if you have a ohm meter and the skill to determine the internal wiring; that would be a datxsheet help. But we should be able to figure out what’s going on. I am inserting the urls for a few close-ups of the caps. 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!
