I assume its a Hitachi, can’t find anything on the interweb on it.

Do you already have an account? Last but not least The schematic shows it like this with the voltages: Then there is Hfe, bandwidth Ft, capacitance Cob and generated noise; which are either irrelevant or relevant, depending on its very datashheet.
Did a couple comparison test graphs. It probably is a 2SC NAD80, I got that scope about 3 years ago locally from craigslist.
If you have ksc – it does better in this respect. So, this is where I need a little help. It’s capacity is also low 2.
Looking at the zoomed circuit image at the beginning, that’s a Baxandal tone control circuit at the left alright.

How does RF play into this? Top grouping is the left transistor and bottom is the right. Lots of DC at the speaker outputs, started testing caps, almost all out of specs and many dead. I only bring this up, as datasgeet was a Sansui thread where the signal had reduced level on one side, and was cured by changing the c to c Notice the knee in the HFE curves below 2 volts.

Waiting for it to come in the mail and may be a future topic here. Share This Page Tweet. This circuit runs at very low collector voltage. By no means an expert but this don’t look dahasheet Very interesting, lots of pics, weak transistor Discussion in ‘ Solid State ‘ started by tbone8Nov 23, 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 stage” with at max a factor 10 amplification probably less than 5 Higher Hfe can sometimes be desired to “unload” the upfront circuit.
The “6” can refer to even narrower Hfe ranking by the factory.
The weak transistor has the legs blackened on it so it musta got hot but not hot enough to kill it? Like the Tek scope. The only downside of the ksc is that its saturation voltage is relatively high.
That might very well be critical in this circuit, and therefore also stick with a SS sub.
Cleaned all the pots and switches, still lots of static. Didn’t work, had a bad cap and bad transistor. No, create an account now. I have a bunch of KSC’s kicking around and wondered if they would work just as well? The digikey link for it is here https: After some assistance getting that fixed, my audio hobby was off and running!
Oilmaster, I saw that SC you posted. First pair of preamp transistors voltages were good but the second pair were way off, right channel one of course.
So KSC should be good enough.

Went through the block diagram in the manual and figgered it had to be one of two transistors on the control board. For all other parameters, the KSC is better. The pinout is different from the original to the SS but I could just put some insulators on the legs and make it fit?
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 datzsheet benifits the distortion levels But the KSC should do fine here.

Below is the block diagram for this. Recapped the whole thing, sounds much better and a microvolt or two of DC at the speakers. The right channel 2sx9014 still weaker than the left. There are also BCc but are base centered. Sounded horrible and right channel weaker than the left. 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.
Yes, my password is: So, what would be the best route to go? The transistor in question datsaheet an HITC6. So I know what I put in. The SS looks good as a replacement.
