Hi,
I am planning to develop a passive phono preamplifier using National LME49710. In the attached document, Figure 2, what exactly is the purpose of the IC's U4 and U5?
Also, I was planning to use Hagerman Bugle power supply. Is this a good match to the pre or do it needs improvement?
Best regards,
BP
