When I say in series I mean that the collector of the 2saA connects directly to the emitter of the 2sa My go to for older transistor or semi-conductor info is datasheetarchive. The “A” suffix means new and improved. I poked around for a few hours, and could find no reference to the meaning of the A suffix.

But I don’t see it on any of the A spec sheets. Do you already have an account? I appreciate the time you put into researching this. Inquiring minds want to know things. Working on a Kenwood KR receiver and suspect one of these of being bad. 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.

Thanks again to all 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.

Now I know what 2sa7733 means, and the parts choices made by Kenwood make more sense based on your description. It is written just like in my OP. Your name or email address: In several previous repair jobs, I failed to find the datasheets of such A version though.

But I did take some live readings, they were pretty close to what the schematic shows. Highly unlikely to be of much relevance. I actually had the datasheet for it on my PC. No, create an account now. JURB – Thanks for the detailed explanation of transistor designations.

ZOOMAug 2, After the reflow it straightened up almost completely It does show Q and P as being hfe ranges. In any case, a mystery is solved, and I have learned a few things here. 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.

They Kenwood did the same thing in the kr manual. Log in or Sign up. Here is L channel, R is almost the same: Is this the VAS, or some other stage? JURBAug 2, 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.

Then I heard another brief cut-out.

I am hesitant to remove them because I have already reflowed once. OilmasterAug 2, Just replace with ksa and call it a day. On the face eatasheet says: The “A” suffix usually ratasheet a higher voltage rating. The red voltage markings on the schema are by Kenwood. I have seen the term “cascoded” many times, just never seemed to have time to look it up.

Good to know about the existence of those Japanese transistor data books too. Where did you come up with a 2SAA? I downloaded the 2SA data sheet but it does not mention the A.

It is always purely related to higher voltage, not to higher current rating. Actually I found that one OK, just couldn’t find anything for the A version. They are also in series? Yes, my password is: JURB – thanks for taking the time to type in those specs for the non-A 2sa
