9014 Datasheet, Equivalent, Cross Reference Search
Do you already have an account? Like the Tek scope. Notice the knee in the HFE curves below 2 volts. For all other parameters, the KSC is better. The SS looks good as a replacement.

Put 1kHz signal through her, signal was clean but the right was half the amplitude of the left channel. That might very well be critical in this circuit, and therefore also stick with a SS sub. So, what would be the best route to go? The “6” can refer to even narrower Hfe ranking by the factory.
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.
Thanks for the replies. The only downside of the ksc is that its saturation voltage is relatively high.

Oilmaster, I saw that SC you posted. OilmasterNov 24, Picked up an old GE A a couple months ago. After some datxsheet getting that fixed, my audio hobby was off and running!
First pair of preamp transistors voltages were good but the second pair were way off, right 2sf9014 one of course. Went through the block diagram in the manual and figgered it had to be one of two transistors on the control board.
If you have ksc – it does better in this respect. By no means an expert but this datashet look good Below is the block diagram for this. No, create an account now.
It’s capacity is also low 2. So I vatasheet what I put in. The pinout is different from the original to the SS but I could just put some insulators on the legs and make it fit? Log in or Sign up. Lots of DC at the speaker outputs, started testing caps, almost all out of specs and many dead.

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. Recapped the whole thing, sounds much better and a microvolt or two of DC at the speakers.
Waiting for it to come in the mail and may be a future topic here. The schematic shows it like this with the voltages: The transistor in question is an HITC6. Makes your life easier as well regarding legs Hfe is not much of issue here as long as it is aboveas this transistor is a “buffer datasjeet with at max a factor 10 amplification probably less than 5 Higher Hfe can sometimes be desired to “unload” the upfront circuit. Did a couple comparison test graphs. There are also BCc but are base centered.
Didn’t work, had a bad cap and bad transistor.
