Also, there is no 2scA, just dataeheet which is the normal complement of 2sa The red voltage markings on the schema are by Kenwood. HyperionAug 2, But it has most things that are not too obscure. JURB – Thanks for the detailed explanation of transistor designations. The “A” suffix usually designates a higher voltage rating.

One channel was intermittent. Here is L channel, R is almost the same: 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.

Now I know 2da733 it means, and the parts choices made by Kenwood make more sense based on your description.

ZOOMAug 2, They Kenwood did the same thing in the kr manual. In several previous repair jobs, I failed to find the datasheets of such A version though. 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.

It does show Q and P as being hfe ranges. Actually I found that one OK, just couldn’t find anything for the A version. Good to know about the existence of those Japanese transistor data books too.

It is always purely related to higher voltage, not to higher current rating. Just replace with ksa and call it a day. Working on a Kenwood KR receiver datashedt suspect one of these of being bad. I can’t see the faces of actual parts well enough to read.

After the reflow it straightened up almost completely 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 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. OilmasterAug 2, I am hesitant to remove them because I have already reflowed once.

In any case, a mystery is solved, and I have learned a few things here.

On the face it says: Turns out there was a 2scA, at least briefly. I have seen the term “cascoded” many times, just never seemed to have time to look it up. The “A” suffix means new and improved.

Inquiring minds want to know things. I downloaded the 2SA data sheet but it does not mention the A. Dayasheet, my password is: ZOOM, I am asking what the dataseet suffix for 2sa means because I want to know what type of part the designers had in mind for this position in the amp.

I actually had the datasheet for it on my PC. But I did take some live readings, they were pretty close to what the schematic shows.

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

JURB – thanks for taking the time to type in those specs for the non-A 2sa The two transistors being discussed are Q15, the 2sa Aand Q17, the 2sa I’m sure it is not as good as those professional trade manuals that you have.
