Manhatten Analog MVP

Bug:

R26, R29, R37 R40 must be a bridge instead of 10K.

improvements for better noise ratio:

install at U4 and U5 a OP275 opamp and swap C1 from 22p to 33p.

furthermore install a 33pF capacitor at U4 and U5 between C5 and C6.

Guide: (extract the Partvalues from the Schematic on the last page in this document). not nice- but what can we do ?

old guide:

BOM tip:

LED holder 3x

Jacks:

LED must be a 2pol red-green 5mm LED

BOM info from old build guide:

Build info:

on mine is an “error”: audio out at the 1+2 out or 3+4 out can't be turnoff completely. attenuation is faulty.

C4 is wrong installed
