Here is the left channel of KR As you pointed out, 2sc is the complement to 2sa, so I would assume that the “A” version of 2sa has similarly increased temperature ratings. What does the A suffix datasgeet

After the reflow it straightened up almost completely Inquiring minds want to know things. Now I know what it means, and the parts choices made by Kenwood make more sense based on your description.

JURB – thanks for taking the time to type in those specs for the non-A 2sa Is this transistor in a high gain position? On the face it says: No, create an account now. The reference is from both the parts list and schematic of Kenwood KR They both had “halo” cracks in their solder joints.

Where did you come up with a 2SAA? OilmasterAug 2, Do you already have an account?

Share This Page Tweet. Thanks again to all The “A” suffix usually designates a higher voltage rating.

In several previous repair jobs, I failed to find the datasheets of such A version though. The red voltage markings on the schema are by Kenwood.

But it has most things that are not too obscure. It does show Q and P as being hfe ranges. Good to know about the existence of those Japanese transistor data books too. But they are only using it 2za733 a current limiter, and my opinion is that it doesn’t mean anything, and is just a glitch that got into their computer.

I actually had the datasheet for it on my PC. My go to for older transistor or semi-conductor info is datasheetarchive.

Yes, my password is: I was able to get a look at one of them with a small lighted magnifier. It is always purely related to higher voltage, not datassheet higher current rating.

ZOOM, I am asking what the “A” suffix for 2sa means because I want to know what type of part the designers had in mind for this position in the amp. Discussion in ‘ Solid State ‘ started by roger2Aug 1, I appreciate the time you put into researching this. Then I heard another brief cut-out. Your name or email address: Also, there is no 2scA, just 2sc which is the normal complement of 2sa Log dahasheet or Sign up. HyperionAug 2, The two transistors being discussed are Q15, the 2sa Aand Q17, the 2sa I downloaded the 2SA data sheet 2xa733 it does not mention the A.


I was looking all over the web for 2saA with no luck: Turns out there was a 2scA, at least briefly. Highly unlikely to be of much relevance. I can’t see the faces of actual parts well enough to read. I checked DC voltages and found a fairly close match to what is shown on the schematic, slightly higher but everything in correct relative proportions.

I poked around for a few hours, and could find no reference to the meaning of the A suffix. Here is L channel, R is almost the same: Is this the VAS, or some other stage?

They Kenwood did the same thing in the kr manual. In any case, a mystery is solved, and I have learned a few things here. I’m sure it is not as good as those professional trade manuals that you have. Actually I found that one OK, just couldn’t find anything for the A version.

Just replace with ksa and call it a day. But I don’t see it on any of the A spec sheets. ZOOMAug 2, When I say in series I mean that the collector of the 2saA connects directly to the emitter of the 2sa
