So, what would be the best route to go?

Top grouping is the left transistor and bottom is the right. Below is the block diagram for this.

You must log in or sign up to reply here. So, this is where I need a little help. Notice the knee in the HFE curves below 2 volts. Waiting for it to come in datasheett mail and may be a future topic here.

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. Just remember, the collector and base need to be crossed to match the original configuration. Log daatasheet or Sign up. OilmasterNov 24, Looking at the zoomed circuit image at the beginning, that’s a Baxandal tone control circuit at the left alright. Ironically, I just bought a Tek that is not working as well.

C Datasheet, 2SC PDF – NPN 50V TR – Usha

First pair of preamp transistors voltages were good but the second pair were way off, right channel one of course. I went to digikey and looked for a hFE TO and the only one that 2sc914 up was a SS, oddly enough had the code.


Then s2c9014 is Hfe, bandwidth Ft, capacitance Cob and generated noise; which are either irrelevant or relevant, depending on its very application. Put 1kHz signal through her, signal was clean but the right was half the amplitude of the left channel. By no means an expert but this don’t look good I only bring datasueet 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 The Q is part of the pre-amp, correct?

That might very well be critical in this circuit, and therefore also stick with a SS sub.

The “6” can refer to even narrower Hfe ranking by the factory. No, create an account now.

If you have ksc – it does better in this respect. Sounded horrible and right channel weaker than the left. How does RF play into this? Sorry so long but I found this real interesting and educational for me. This circuit runs at very low collector voltage.

In other words, a higher Hfe means that less current needs 2sc9104 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. The weak transistor has the legs blackened on it so it musta got hot but not hot enough to kill it?

The digikey link for it is here https: Oh, and I would obviously replace the pair. I assume its a Hitachi, can’t find anything on the interweb on it. Yes, my password is: Like the Darasheet scope. Very interesting, lots of pics, weak transistor Discussion in ‘ Solid State ‘ started by tbone8Nov 23, So I know what I put in.

Went through the block diagram in the manual and figgered it had to be one of two transistors 2sc9041 the control board. Oilmaster, I saw that SC you posted. Do you already have an account? I would certainly ensure to have a simular bandwidth.

There are also BCc but are base centered. So KSC should be good enough. Assuming this is a good replacement, I guess a guy could bend the leads and squirrel datasheeet in. After some assistance getting that fixed, my audio hobby was off and running! Didn’t work, had a bad dahasheet and bad transistor. But if the lower bandwidth would have been acceptable for the circuit, then the equipment manufacturer would have put it!

Discussion in ‘ Solid State ‘ started by tbone8Nov 23, The schematic shows it like this with the voltages:
