Bat VK P3 phono board


I am currently looking at doing some work on my Bat VK3i preamp which I have had since new as its exhibiting some evidence of dry joints.  I will be upgrading some parts which I can identify with the help of a technician but I am unable to identify the opamps used on the solid state VK P3 phono board. Just wandering if anyone have worked on the VK 3P and have some idea of what op amps BAT used on the board.  Thanks Regards Alan

What do you mean by “evidence of dry joints. I have a VK 3ix that I just had the 6 pak mod done too. 

Just curious So I can keep my eye out on it
