Hello, now we come to the third b ilding instr ction. In this man al we will assemble the
-stereo m ltimode filter.
As always, take a look at the board first – and Hoooommmmm -, the only thing yo have to
watch o t for is that the three connectors K1,2,3,4 come down.
Tip: the resistors sho ld always be meas red with a m ltimeter before soldering.
People who want to so rce parts by themselves - Attention both IC's 4052 m st be
C-Mos IC's are. These work with a higher operating voltage of 8 Volt!
first we will solder in the coils/resistors, then the capacitors, then the IC sockets and finally
the transistors and potentiometers.
Everything ready ?
Here is first of all the layo t .

We now solder the following components :
