I am going to replace transistor!! Please warn me if doing wrong! Thread starter Willen Start date Jul 14, Willen Well-Known Member Jul 14, Look this one first- www. We see T1, T2, T3.

I am going to replace transistor!! Please warn me if doing wrong!

Please match your transistor fatasheet to these designators. The original circuit used good high frequency transistors but you are using ordinary “general purpose” transistors that might melt with a supply that is as high as 12V. The 2N is OK.

I would guess that general purpose transistors might work for T1 and T2, but T3 would need to be a wide band RF device. Not sure the will cut it: Design is working efficiently well using 2N devices.

There is no point, i feel, inchanging devices for the sake of changing. Datashset Well-Known Member Jul 15, dxtasheet An old 2N is in an old metal case. I have never seen nor used one. Its maximum allowed heating is only mW but the max allowed heating is mW for a newer 2N A 2N has better high frequency gain than a 2N but both have much less gain than the microwave transistors in the original project.

If the original project has an output of mW then with the general purpose transistors its output might be only 50mW. Willen Well-Known Member Jul 16, Now I have hundreds of PN plastic. I still have some old BC transistors in the same old metal case as an old 2N I haven’t used them for about 46 years but they probably still work.

A 2N in the output should increase the power OK with a heatsink. You must log in or register to reply here. Replacement Transformer Started by ncag Today at 7: Datasheets, Manuals or Parts.
