Hi ivconic

If you please translate this page to to me and what the signal Is ?

Is it dumping signal and if its whats the relationship between it and r37

On the schematic r37 is the sound output

Regards

"...First diagram is showing over damped signal, measuring point is junction between R37 and diode pair D16/D17..."
"...Second diagram is showing properly damped signal, measuring point is junction between R37 and diode pair D16/D17..."

That's rough translation.
Now looking at schematic i see why are you asking, yes it does not make any sense, you are right!
I guess it's a typo in the book. Most probably author made mistake.
I guess what he meant is junction between R17 and diode pair D14/D15.
Usually i don't pay attention on such details, so i missed to spot that mistake until now.
Good!

... which just reminds me to repeat again here several other mistakes, might be helpful;

"...DBP2010 error list:
Main PCB
T4 & T5 (Collector & Emitter twisted by 180 degree)
R38 = 1 Ohm
R34 need to be optimized
Modul PCB
T3 (Collector & Emitter twisted by 180 degree)..."

I got these from Chris.
Cheers Chris!

Thanks for translation what u said is most logic the diodes are 14 and 15 and r17 cos d16 and d17 in the


Power stage and won't oscillate at about 55khz or 18.8 microsecond

About mistakes i own original dbp 2010 thats why i have no errors when contrast new set

Regards
