Build documentation for:

continuum phaser ii

An original design by

Frequency central

Rev 3 / May 2014

Main PCB:

Panel PCB:

Key to PCB screen print:

n: This signifies NPN BC547 transistors. Note the correct pinout as shown by the half circles.

p: This signifies PNP BC557 transistors. Note the correct pinout as shown by the half circles.

Please observe that the TL084 is 'the other way round' with respect to the LF351 and 2 x

LM13700.

Please observe the correct polarity of the 2 diodes and 8 electrolytic capacitors. The 6 x

22uF are configured in sets of 2 back to back (negative to negative).
