This gives you a standard in which you can figure out other conditions with different component values. You must log in or sign up to reply here. The 2SA I received from Futurlec had disappointing gain results, I tossed those transistors into the garbage. Beta or Gain or hFE. Just have to make sure dataaheet put the Emitter pin of the transistor into the “E” hole.

BassblasterOct 29, You will then see datasheeh eat crow on my previous comments. Line a pie plate with pie crust and line with slices of hard-boiled egg.

SargentRickoOct 29, No big deal, I will just install these transistors with the flat side in the opposite direction. The end, and definitely not a happy one.


The KSC transistor is obsolete and not available. Place crow meat on top. It’s life is unpredictable, but evidence is that it will outlast the other components in the circuit. SargentRickoOct 24, So I thought I would check out the other Pioneer suggested substitution: ZOOMOct 29, Hmmm Which one to choose?

The fakes are always green, and always with the 6F code. This is the ratasheet gain or amplification factor. The Gain is much higher than I expected, and better than the one I pulled out. I see on my Tuner Board Parts list that I have two of them. Watthour thanks for the advice. Also, there are procedures to follow when installing them modules.

Identifies the “B” value aka: WatthourOct 26, Do not bake Make a medium thick gravy with flour, shortening, and juices in which the crow has cooked and let cool. Try downloading it it is not there. As ZOOM indicated, and new modules you get are almost certainly going to be aftermarket copies, sometimes of very dubious quality. WatthourOct 23, Most br255 conditions are presented with set values for the components.

Your A is fake, guaranteed. Your only option is KSA, which is a fine one. You can get fakes from Ebay or whatever, sure, but they will not perform as they should, if at all.

Here are a few links i found on Google. datzsheet

SK was started by RCA. WatthourOct 28, Prev 12 13 14 15 16 dataasheet 18 19 20 21 22 Next Page 17 of Wrong beta, should be higher.

Here is another related link. Search results Pinout http: But I think that the higher the Beta on the transistor the better the amplification. MSP in Service Manuals.

Loosen joints with a knife but do not cut through. Sorry to come off so strong but it bothers me when people make comments and say it took a few seconds on Google but, the Datasheet is nowhere to be found.
