Dirisar Good to know about the existence of those Japanese transistor data books too. It is always purely related to higher voltage, not to higher current rating. Do you already have an account? They Kenwood did the same thing in the kr manual. One channel was intermittent.

Dirisar Good to know about the existence of those Japanese transistor data books too. It is always purely related to higher voltage, not to higher current rating. Do you already have an account? They Kenwood did the same thing in the kr manual. One channel was intermittent. Is this the VAS, or some other stage? You must log in or sign up to reply here.
Highly unlikely to be of much relevance. Inquiring minds want to know things. Also, there is no 2scA, just 2sc which is the normal complement of 2sa I downloaded the 2SA data sheet but it does not mention the A.
It is written just like in my OP. I appreciate the time you put into researching this. Where did you come up with a 2SAA? I actually had the datasheet for it on my PC. Just replace with ksa and call it a day. But I did take some live readings, they were pretty close to what the schematic shows.
Your name or email address: Turns out there was a 2scA, at least briefly. The reference is from both the parts list and schematic of Kenwood KR In any case, a mystery is solved, and I have learned a few things here. I was able to get a look at one of them with a small lighted magnifier. After the reflow it straightened up almost completely Log in or Sign up.
The red voltage markings on the schema are by Kenwood. HyperionAug 2, My go to for older transistor or semi-conductor info is datasheetarchive. Here is L channel, R is almost the same: Then I heard another brief cut-out. Is this transistor in a high gain position? Here is the left channel of KR They are also in series?
Working on a Kenwood KR receiver and suspect one of these of being bad. Share This Page Tweet. Related Posts
