JURB – Thanks for the detailed explanation of transistor designations. Yes, my password is: But I did take some live readings, they were pretty close to what the schematic shows. They are also in series?
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. Is this transistor in a high gain position? I downloaded the 2SA data sheet but it does not mention the A. 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. I actually had the datasheet for it on my PC.
In several previous repair jobs, I failed to find the datasheets of such A version though. Discussion in ‘ Solid State ‘ started by roger2Aug 1, ZOOMAug 2, One channel was intermittent. The two transistors being discussed are Q15, the 2sa Aand Q17, the 2sa 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.
Working on a Kenwood KR receiver and suspect one of these of being bad. Just replace with ksa and call it a day.

The red voltage markings on the schema are by Kenwood. Do you already have an account? They Kenwood did the same thing in the kr manual. After the reflow it straightened up almost completely I appreciate the time datashee put into researching this. No, create an account now. The “A” suffix means new and improved.

I’m sure it is not as good as those professional trade manuals that you have. HyperionAug 2, Inquiring minds want to know things. Also, there is no 2scA, just 2sc which is the normal complement of 2sa My go to for older transistor or semi-conductor info is datasheetarchive. I have seen the term “cascoded” many times, just never seemed to 2s733 time to look it up.
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 it has most things that are not too obscure.
The reference is from both the parts list and schematic of Kenwood Eatasheet On the face it says: I was looking all over the web for 2saA with no luck: Here is L channel, R is almost the same: OilmasterAug 2, Highly unlikely to be of much relevance. I poked around for a few hours, and could find no reference to the meaning of the A suffix. 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.

Your name or email address: Here is the left channel of KR Is this the VAS, or some other stage? JURB – thanks for taking the time to type in those specs for the non-A 2sa I am hesitant to remove them because I have already reflowed once.
The “A” suffix usually designates a higher voltage rating. Turns out there was a 2scA, at least briefly. JURBAug 2, But I don’t see it on any of the A spec sheets.
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. When I say in series I mean that the collector of the 2saA connects directly to the emitter of the 2sa Share This Page Tweet.
Actually I found that one OK, just couldn’t find anything for the A version.
