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. When I say in series I mean that the collector of the 2saA connects directly to the emitter of the 2sa Good to know about the existence of those Japanese transistor data books too.

It is written just like in my OP. 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. Is 2aa733 the VAS, or some other stage? They both had “halo” cracks in their solder joints.

Inquiring minds want to know things. HyperionAug 2, One channel was intermittent. What does the A suffix mean? But it has most things that are not too obscure. On the face it says: Then I datashete another brief cut-out.

Also, there is no 2scA, just 2sc which is the normal complement of 2sa I can’t see the faces datsheet actual parts well enough to read.

I was looking all over the web for 2saA with no luck: Highly unlikely to be of much relevance. They Kenwood did the same thing in the kr manual.

After the reflow it straightened up almost completely 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. It is always purely related to higher voltage, not to higher current rating. In several previous datashset jobs, I failed to find the datasheets of such A version though. In any case, a mystery is solved, and I have learned a few things here.

Actually I found that one OK, just couldn’t find anything for the A version. 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. Discussion in ‘ Solid State ‘ started by roger2Aug 1, Your name or email address: Yes, my password is: It does show Q and P as being 2da733 ranges. Just replace with ksa and call it a day. Here is the left channel of KR Where did you come datqsheet with a 2SAA?


You must log in or sign up to reply here. The “A” suffix means new and improved. I am hesitant to remove them because Datasheett have already reflowed once. My go to for older transistor or semi-conductor info is datasheetarchive.

I actually had the datasheet for it on my PC. Is this transistor in a high gain position?

The “A” suffix usually designates a higher voltage rating. No, create an account now. OilmasterAug 2, I have seen the term “cascoded” many times, just never seemed to have time to look it up. JURB – thanks for taking the time to type in those specs for the non-A 2sa I’m sure it is not as good as those professional trade manuals that you have.

The reference is from both the dataaheet list and schematic of Kenwood KR I was able to get a look at one of them with a small lighted magnifier. Log in or Sign up. Working on a Kenwood KR receiver and suspect one of these of being bad. JURBAug 2,
