Sorry so long but I found this real interesting and educational for me.

2SC datasheet, 2SC datasheets, manuals for 2SC electornic semiconductor part

OilmasterNov 24, But if the lower bandwidth would have 2scc9014 acceptable for the circuit, then the equipment manufacturer would have put it! For all other parameters, the KSC is better. The SS looks good as a replacement. Catasheet, I just bought a Tek that 2s9c014 not working as well. Just remember, the collector and base need to be crossed to match the original configuration. I assume its a Hitachi, can’t find anything on the interweb on it.

So KSC should be good enough. Recapped the whole thing, sounds much better and a microvolt or two of DC at the speakers. When subbing transistors, you’ll make sure that the allowable Vce, IC and Pc are safely above in-circuit conditions, and certainly not lower then originally installed unless you can deduct what worst-case in-circuit current can be most often only a few mA runs while the transistor is ranked mA, so a 50mA ranked sub-transistor could do as well.



Waiting for it to come s2c9014 the mail and may be a future topic here. Top grouping is the left transistor and bottom is the right.

Picked up an old GE A a couple months ago. If you have ksc – it does better in this respect. Cleaned all the pots and switches, still lots of static.

By no means an expert but this don’t look good How does RF play into this? Went through the block diagram in the manual and figgered it had to be one of two transistors on the control board.

2N / BC / PN / 2N NPN Transistor – NTEAP

Put 1kHz signal through her, signal was clean but the right was half the amplitude of the left channel. The right channel was still weaker than the left. So, this is where I need a little 2ec9014.

The darasheet downside of the ksc is that its saturation voltage is relatively high. Below are screen captures 2dc9014 the DCA pro traces. Looking at the 2SC datasheet, its Ft is rather high at Mhz, so it’s not the average audio AF transistor, more like a tuning circuit transistor RF.

No, create an account now. It’s capacity is also low datashet. Discussion in ‘ Solid State ‘ started by tbone8Nov 23, NAD80Nov 24, Desoldered the good side one and it had an hFE of almost I went to digikey and looked for a hFE TO and the only one that popped up was a SS, oddly enough had the code.


Oh, and I would obviously replace the pair. After some assistance getting that fixed, my audio hobby was off and running! Log in or Sign up.

Did a couple comparison test graphs. I see now that it is indeed the pre-amp section. Sounded horrible and datashewt channel weaker than the left. Oilmaster, I saw that SC you posted.

Assuming this is a good replacement, I guess a guy could bend the leads and squirrel it in. Makes your life easier ddatasheet well regarding legs Hfe is not much of issue here as long as it is aboveas this transistor is a “buffer stage” with at max a factor 10 amplification probably less than 5 Higher Hfe can sometimes be desired to “unload” the upfront circuit. Below is the block diagram for this.

The digikey link for it is here https: The schematic shows it like this with the voltages: Didn’t work, had a bad cap and bad transistor. The pinout is different from the original to the SS but I could just put some insulators on the legs and make it fit?

Last but not least I only bring this up, as there was a Sansui thread where the signal had reduced level on one side, and was cured by changing the c to c
