Thanks again to all 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.

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

JURBAug 2, It is written just like in my OP. I poked around for a few hours, and could find no reference to the meaning of the Dataseet suffix. They are also in series? Good to know about the existence of those Japanese transistor data books too.

Даташиты 2SA, 2SALT1.

But they are only using it as a current limiter, and 2sa73 opinion is that it doesn’t mean anything, and is just a glitch that got into their computer. The “A” suffix means new and improved. Inquiring minds want to know things. I have had a look around for this, trying to datashret references to the 2SAA as distinct from the 2SA and can’t find anything worthy of note.

Then I heard another brief cut-out. What does the A suffix mean? You must log in or sign up to reply here. Do you already have an account? The reference is from both the parts list and schematic of Kenwood KR I have seen the term “cascoded” many times, just never seemed to have darasheet to look it up.

When I say in series I mean that the collector of the 2saA connects directly to the emitter of the 2sa 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. ZOOMAug 2, But I don’t see it on any of the A spec sheets.

Discussion in ‘ Solid State ‘ started by roger2Aug 1, Actually I found that one OK, just couldn’t find anything for the A version. I downloaded the 2SA data sheet but it does not mention the A. Also, there is no 2scA, just 2sc which is the normal complement of 2sa It is always purely related to higher voltage, not to higher current rating.

Where did you come up with a 2SAA? I can’t see the faces of actual parts well enough to read. On the face it says: HyperionAug 2, The datasheef suffix usually designates a higher voltage rating. It does show Q and P as being hfe ranges.

But I did take some live readings, they were pretty close to what the schematic shows. Here is L channel, R is almost the same: I actually had the datasheet for it on my PC. Working on a Kenwood KR receiver and suspect one of these of being bad.

I datasheey the time you put into researching this. Your name or email address: Is this the VAS, or some other stage? Yes, my password is: No, create an account now. Here is the left channel of KR 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.

I was able to get a look at one 2ssa733 them with a small lighted magnifier.
