2SC9014 TRANSISTOR DATASHEET PDF

Fejora But if the original transistor has a high gain, try to match it. If the lead arrangement of a small replacement transistor differs from that of the the original, you can sometimes bend the transistor leads across one another to route them into the correct holes in the circuit board. BV DSS — the breakdown voltage between the Drain and the Source terminals when the gate is short-circuited to the source. Knowing how to substitute an alternate transistor type can speed up your repair, or make an otherwise impossible repair possible.

Kazimuro First pair of preamp transistors voltages were good but the second pair were way off, right channel one of course. This circuit runs at very low collector voltage. In other words, a higher Hfe means that less current needs to be supplied by the upfront section aka higher Hfe provides higher input impedance The very linear Hfe-Ic curve of the also provides an excellent linearity of the buffer stage which benifits the distortion levels But the KSC should do fine here.

So KSC should be good enough. Below is the block diagram for this. Log in vatasheet Sign up. But if the lower bandwidth would have been acceptable for the circuit, then the equipment manufacturer would have put it!

NAD80, I got that scope about 3 years ago locally from craigslist. Picked up an old GE A a couple months ago. The weak transistor has the legs blackened on it so it musta got hot but not hot enough to kill it? The SS looks good as a replacement. Then there is Hfe, bandwidth Ft, capacitance Cob and generated noise; which are either irrelevant or relevant, depending on its very application.

Oilmaster, I dataxheet that SC you posted. Like the Tek scope. Recapped the whole thing, sounds much better and a microvolt or two of DC at the speakers. The transistor in question is an HITC6. Did a couple comparison test graphs. Daatasheet went to digikey and looked for a hFE TO and the only one that popped up was a SS, oddly enough had the code. The pinout is different from the original to the SS but I could just put some insulators on the legs and make it fit?

After some assistance getting that fixed, my audio hobby was off and running! So I know what I put in. Cleaned all the pots and switches, still lots of static. Oh, and I would obviously replace the pair.

Put 1kHz signal through her, signal was clean but the right was half the amplitude of the left channel. No, create an account now. So, what would be the best route to go? Went through the block diagram in the manual and figgered it had to be one of two transistors on the control board. The only downside of the ksc is that datasgeet saturation voltage is relatively high. Sorry so long but I found this real interesting and educational for me.

Thanks for the replies. You must log in or sign up to reply here. The Q is part of datasheef pre-amp, correct? Related Posts.
