I was looking all over the web for 2saA with no luck: You must log in or sign up to reply here. Discussion in ‘ Solid State ‘ started by roger2Aug 1, I can’t see the faces of actual parts well enough to read.

It is always purely related to higher voltage, not to higher current rating.

HyperionAug 2, I downloaded the 2SA data sheet but it does not mention the A. Highly unlikely to be of much relevance. The red voltage markings on the schema are by Kenwood.

Actually I found that one OK, just couldn’t find anything for the A version. After the reflow it straightened up almost completely What does the A suffix mean? Here is the left channel of KR I was able to get a look at one of them with a small lighted magnifier. Good to know about the existence of those Japanese transistor data books too. In any case, a mystery is solved, and I have learned a few things here.

But I don’t see it on any of the A spec sheets. Inquiring minds want to know things.

what does (A) suffix mean in 2SA (A) (Q,P) ??? | Audiokarma Home Audio Stereo Discussion Forums

Working on a Kenwood KR receiver and suspect one of these of being bad. The “A” suffix means new and improved.

Where did you come up with datasjeet 2SAA? Now I know what it means, and the parts choices made by Kenwood make more sense based on your description. I poked around for a few hours, and could find no reference to the meaning of the A suffix. Yes, my password is: Then I heard another brief cut-out. The vatasheet transistors being discussed are Q15, the 2sa Aand Q17, the 2sa In several previous repair jobs, I failed to find the datasheets of such A version though.

OilmasterAug 2, If you really need to replace it, just make sure that the voltage between C-B doesn’t exceed 60V, and between C-E doesn’t exceed 50V. JURBAug 2, Is this the VAS, or some other stage? Here is L channel, R is almost the same: It is written just like in my OP.


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. Is this transistor in a high gain position? But it has most things that are not too obscure. JURB – thanks for taking the time to type in those specs for the non-A 2sa Your name or email address: Do you already have an account?

I’m sure it is not as good as those professional trade manuals that you have.

Thanks again to all It does show Q and P as being hfe ranges. Also, there is no 2scA, ratasheet 2sc which is the normal complement of 2sa No, create an account now. I have had a look around for this, trying to find references to the 2SAA as distinct from the 2SA and can’t find anything worthy of note.

I appreciate the time you put into researching this.
