I ve got a NG51s, many faulty parts have been replaced already
As I m new to this little mashine, I can t compare it to a other working one.
First Question:
"Nachhallstärke" works perfekt until a quarter turn, after that it gets too loud and while turning it up, it soon gets more distorted than the first picked note.
In other words there is more echo boost than preamp boost. Is this normal?
All trimpots are changed to new ones and I don t know their original settings.
R17 Eingangspegel is understandable for me (But 95% of its turningway it is too loud and overloads the echounit)
I don t understand R52 and R46, how to adjust them.
Where the shematic shows two 100K my echounit has two 220K
