KR-9600 outputs

The diff-pairs in the 9600 are NPN. The KSC1845 will do well.

Hi i checked the d.c offset at the speaker terminals and they are both around 85mv every kenwood kr9600 seems to have this same measurement.

When a 9600 leaves my bench, offset is about 2~5mV and steady.

Thanks for the correction, it's been awhile since I've had one here. Apparently I've got Pioneer diffs on the brain.

The three kenwood kr9600's I have had seem to all have the high dc offset around 85mv and I do rember when they turn on and the relay the meters go up a hair and you can hear a faint click in speakers Does anyone know what the stock new kenwoods dc offset would be? they all worked well for years This recent one I have works well too but I am just curious what they were originally? I like the idea of swiching the transistors to get it down to 5mv

Stk 1050 ?

Here is a shot of an STK module I made for my 9600.
Been in daily use for about 20 years.

Is that an STK 1050 V ? Or stk 4050 V ??
4050 V - I think. Very cool.
Thanks.
