JURB – thanks for taking the time to type in those specs for the non-A 2sa Thanks again to all 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.
JURBAug 2, Also, there is no 2scA, just 2sc which is the normal complement of 2sa Do datashewt already have an account? But I did take some live readings, they were pretty close to what the schematic shows. 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.
ZOOM, I am asking what dtaasheet “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.
ZOOMAug 2, As you pointed out, 2sc is the complement to 2sa7333, so I would assume that the “A” version of 2sa has similarly increased temperature ratings. Actually I found that one OK, just couldn’t find anything for the A version.
Inquiring minds want to know things. They Kenwood did the same thing in the kr manual. What does the A suffix mean? I was looking all over the web for 2saA with no luck: They are also in series? Here is L channel, R is almost the same: Just replace with ksa and call it a day. Is this the VAS, or some other stage?
Turns dztasheet there was a 2scA, at least briefly. No, create datasjeet account now. Now I datashert what it means, and the parts choices made by Kenwood make more sense based on your description. One channel was intermittent. Discussion in ‘ Solid State ‘ started by roger2Aug 1, JURB – Thanks for the detailed explanation of transistor designations. 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. Share This Page Tweet. Your name or email address: The red voltage 2ss733 on the schema are by Kenwood.

But I don’t see it on any of the A spec sheets. When I say in series I mean that the collector of the 2saA connects directly to the emitter of the 2sa Is this transistor in a datahseet gain position?
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. I actually had the datasheet for it on my PC. Yes, my password is: 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. Where did you come up with a 2SAA?
I appreciate the time you put into researching this.
what does (A) suffix mean in 2SA733 (A) (Q,P) ???
It is written just like in my OP. The reference is from both the parts datawheet and schematic of Kenwood KR I’m sure it is not as good as those professional trade manuals that you have. Log in or Sign up. The “A” suffix means new and improved. In any case, a mystery is solved, and I have learned a few things here. Highly unlikely to be of much relevance. You must log in or sign up to reply here. It is always purely related to higher voltage, not to higher current rating.
I am hesitant to remove them because I have already reflowed once. They both had “halo” cracks in their solder joints.
