2SC2509 ?
Anyone out there know where I can buy a couple of 2SC2509 transistors?
Any help will be greatly appreciated. Theo |

Theo These sites indicate that they have stock: http://www.mcmelectronics.com/product/2SC2509 and http://www.ceitron.com/semi/semi.phtml?part=2SC2509+ -- Dave M MasonDG44 at comcast dot net (Just substitute the appropriate characters in the address) Life is like a roll of toilet paper; the closer it gets to the end, the faster it goes. |

Does anyone know what the equivalent is to the 2SC2509 so I can search for that too? |

Does anyone know what the equivalent is to the 2SC2509 so I can search for that too? It looks as if ECG236 is one possible substitute, and 2SC1945 is another. You might also check out 2SC1969 and MRF-485... depending on your application they might work. Kenwood apparently recommends the 2SC3133 as a substitute in the TS-450. The lead configurations for these substitutes may be different and require lead-swapping, and other parts changes may be required when using substitute transistors. Beware of possible fake/forged/counterfeit parts. I believe I've seen some mod workups for CB rigs, which substitute an entirely different sort of part (e.g. the IRF510) as an RF driver or final. Using the IRF510 or similar MOSFETs as RF finals requires substantial circuit modification, and from what I've heard the efficiency is likely to be poor if you're driving them from a 12-volt supply. -- Dave Platt AE6EO Friends of Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |

I was going to make another 222 transverter from W1GHZ, but the stupid helical filters aren't available anymore (I think Digikey still has some but they want $48 each for a 222 three pole filter. That's nuts! So, I have a blank board and I'm going to try to make a simple filter and see if I can make it work...I've been "build crazy" for the past couple years and it's getting harder and harder! You have to pretty much build something very soon after it appears in a magazine or some part will go obsolete and you're stuck... Scott N0EDV |

HI
Also try http://www.jabdog.com/semi-tra6.htm for 2SC1969 while stocks last. Sadly no 2SC2509s though. Watch out though. Looking on http://www.modecomponents.co.uk/ under the Transistors section it states: Due To Mitsubishi discontinuing the below devices and so many fakes on the market I am no longer stocking them. 2SC1969 is one of the listed items. 73 John -- www.wells10000.plus.com/m5aml "raypsi" wrote in message ...
