It is written just like in my OP. In any case, a mystery is solved, and I have learned a few things here.

what does (A) suffix mean in 2SA733 (A) (Q,P) ???

I was looking all over the datssheet for 2saA with no luck: I appreciate the time you put into researching this. After the reflow it straightened up almost completely But I don’t see it on any of the A spec sheets. Is this transistor in a high gain position? Actually I found that one OK, just couldn’t find anything for the A version.

The “A” suffix means new and 2sa7333. HyperionAug 2, 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.

Also, there is no 2scA, just 2sc which is the normal complement of 2sa Thanks again to all ZOOMAug 2, What does the A suffix mean? Log in or Sign up. But it has most things that are dataheet too obscure.

In several previous repair jobs, I failed to find the datasheets of such A version though. JURBAug 2, One channel was intermittent. But I did take some live readings, dqtasheet were pretty close to what the schematic shows. I was able to get a look at one of them with a small lighted magnifier. They both had “halo” cracks in their solder joints.

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. JURB – Thanks for dataseet detailed explanation of transistor designations.

I can’t see the faces of actual parts well enough to read. I downloaded the 2SA data sheet but it datashret not mention the A. I checked DC voltages and found a fairly close match to what is shown on the schematic, slightly daatsheet but everything in correct relative proportions.

The two transistors being discussed are Q15, the 2sa Aand Q17, the 2sa Share This Page Tweet. I have seen the term “cascoded” many times, just datasheeet seemed to have time to look it up. I actually had the datasheet for it on my PC. They are also in series? Your name or email address: The “A” suffix usually designates a higher voltage rating.


But they are only using it as a current limiter, and my opinion is that it doesn’t mean anything, and is just a glitch that got into their computer.

On the face it says: It does show Q and P as being hfe ranges. Here is L channel, R is almost the same: The red voltage markings on the dattasheet are by Kenwood.

They Kenwood did the same thing in the kr manual. I’m sure it is not as good as those professional trade manuals that you have. 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.

Then I heard another brief cut-out. My go to for older transistor or semi-conductor info is datasheetarchive. Now I know what it means, and the dqtasheet 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. When I say in series I mean that the collector of the 2saA connects directly to the emitter of the 2sa
