By no means an expert but this don’t look good The SS looks good as a replacement. You must log in or sign up to reply here. So Datashfet know what Datasneet put in. Went through the block diagram in the manual and figgered it had to be one of two transistors on the control board. Log in or Sign up. With all that, you can select the right sub Now, if you look at the newly SS transistorthen you’ll notice that it is an exact sub for the 2SC including EBC pin layoutand I would thus very much use that one.

Ironically, I just bought a Tek that is not working as well.

Notice the knee in the HFE curves below 2 volts. The transistor in question is an HITC6. How does RF play into this? Oh, and I would obviously replace the pair.

Below is the block diagram for this. Picked up an old GE A a couple months ago. 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. Last but not least So KSC should be good enough.

Top grouping is the left transistor and bottom is the right. I would certainly ensure to have a simular bandwidth. If you have ksc – it does better in this respect. The Q is part of the pre-amp, correct? Did a couple comparison test graphs. Oilmaster, I saw that SC you posted. 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.

Very interesting, lots of pics, weak transistor | Audiokarma Home Audio Stereo Discussion Forums

Recapped the whole thing, sounds much better and a microvolt or two of DC at the speakers. The schematic shows it like this with the voltages: Looking at the zoomed circuit image at the beginning, that’s a Baxandal tone control circuit at the left alright.

I have a bunch of KSC’s kicking around and wondered if they would work just as well? The only downside of the ksc is that its saturation voltage is relatively high.

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 Yes, my password is: Share This Page Tweet.

For all other parameters, the KSC is better. Your name or email address: So, what would be the best route to go? Dxtasheet remember, the collector and base need to be crossed to match the original configuration. That might very well be critical in this circuit, and therefore also stick with a SS sub.

There are also BCc but are base centered. 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.

Sounded horrible and right channel weaker than the left. Put 1kHz signal through her, signal was clean but the right was half the amplitude of the left channel. Discussion in ‘ Solid State ‘ started by tbone8Nov 23, Thanks for the replies. Cleaned all the pots and switches, still lots of static. Lots of DC at the speaker outputs, started testing caps, almost all out of specs and many dead. I see now that it is indeed the pre-amp section. It’s capacity is also low 2.

It probably is a 2SC OilmasterNov 24,
