PPI PC2350 line drivers

Staykov · 08:10 AM

Hi guys, I need you to help me with this amplifier.
I'm looking for line driver board on the pic.
The part numbers are 09-2515-1000 IR0032. I'd really appreciate it if you could tell me something about schematic or if you have spare one like this.

Try THIS.

What's wrong with the ones in your amp?

"Cold Solder" problem.
... not sure, but there is chance for faulty paint resistors on the board(blue color).

The only ones that I've seen fail are behind the large driver transistors. If you measure 100 ohms between the pins on the ends of the board and the emitters of the large driver transistors, they are OK.
