sanyo dca 20

raindog · 7th June 2009, 10:59 AM

Hi everybody,

A friend gave me a Sanyo dca 20 amp a few days ago and when I've took it apart I've had a nasty surprise: some ,, genius " replaced the power amp ic whith a cheap solid state module

( fortunately he didn't destroy the PCB ). I was wondering if anybody knows what ic this amp originaly had.

Thanks

Paul

Show some pics.

Im guessing the original poweramp was a stk module, such as STK4152 or similar.

I'll post some pics when I'll find my camera ( hopefully soon ) but I think you are right Tekko , the pcb indicates a 16 pin ic , supply voltage is +/- 30v ( 60volts total ) and on the back 8 ohm speakers . I personaly was thinking stk465.
