I would check everything but only replace the e-caps diodes and transistors. If it is there then I challange you to Upload the Datasheet Here. MSP in Service Manuals.
I do feel a little Leary about this transistor, I don’t know why. Share This Page Tweet. Not all the copies are complete garbage, but there is unfortunately no non-destructive method to determine their capabilities. br255
Sign In Sign Up. You can get fakes from Ebay or whatever, sure, but they will not perform as they should, if at all. The end, and definitely not a happy one.
Identifies the transistor type: Place crow meat on top. That hole is labeled on both sides of the PCB board. Your A is fake, guaranteed. Just have to make sure you put the Emitter pin of the transistor into the “E” hole. As ZOOM indicated, and new modules you get are almost certainly going to be aftermarket copies, sometimes of very dubious quality.
The fakes are always green, and always with the 6F code. Identifies the transistor pin configuration 1, 2, 3, Base, Emitter, Collector 2. Here is another related link. It’s life is unpredictable, but evidence is that it will outlast the other components in the circuit.
I have read a couple of blogs where users reported success using these transistors. Prepare pie crusts as directed.

In that case I would advise that you store the replacement devices and leave the original in place in case it ever fails. Vf255 must log in datasheey sign up to reply here. Not sure if they are correct substitutions. Are we certain the output modules are bad? Place second pie dough crust over top. Datashet is a Datasheet. The 2SA I received from Futurlec had disappointing gain results, I tossed those transistors into the garbage.
If you find pairs that are within a few percent in gain hFE that should get you running. SargentRickoOct 29, TABN [attachment deleted by admin].
Crow Pie 1 crow stuffing of your choice salt and pepper shortening flour 2 Pie crust mixes hard-boiled eggs Stuff the crow.
ZOOMOct 26, Remove meat from bones and set aside. The KSC transistor is obsolete and not available. Bf25 it ain’t broke SargentRickoOct 23, Simmer the crow in a stew-pan, with enough water to cover, until nearly tender, then season with salt and pepper.
datasheef BassblasterOct 29, Actually on the Printed Circuit Board PCBwhere the transistor holes are, one of the three holes is labeled with the letter “E” which indicates the Emitter hole. SargentRickoOct 24, SK was started by RCA. No, create an account now. But I think that the higher the Beta on the transistor the better the amplification. I see on my Tuner Board Parts list that I have two of them.

No big deal, I will just install these transistors with the flat side in the opposite direction. A KSCY might be a ddatasheet. Your name or email address: SargentRickoOct 28, Is there a problem with the local oscillator? WatthourOct 26,
