Title: Clear U47 Circuit Diagram
Post by: DanDan on April 15, 2021, 03:52:57 PM

The common  U47 schematic knocking around seems to be a photo, not very clear.  I have searched quite a few times for a High Resolution image of a U47 Schematic. Anyone got one?

Send me your email address and the approximate series/date of manufacture of the U47 you are interested in, and I will scan you the schematic.
