Stemfoort Compact Disc Player : no analog audio

The Stemfoort Compact Disc Player  is an Sugden SDT-1 copy

 

 

based on Philips “CD – ENGINE II INDUSTRIAL SUPPLIES”

 

 

spdif connection ?!

spdif from a PCF2705

Lets check is there is signal going to the input of the SAA7220 on the Pins of the SAA7220 itself ?

No

Bad connects ?!

Yes,  there it is

Had to add 5 pins to get signal to the TDA1541A 😉

 

Replaces the IC-sockets

Better i think 😉

Also the TDA1541(A) S1  is faulty ;-(
