Barton BMC082 Triangle Frequency Doubler

This module consists of four triangle frequency doubling circuits. The circuit board normalizes the output of each doubling circuit to the input of the next so that it can easily be used to multiply frequency by 4, 8 or 16.
Other waveforms can be used instead of triangles but there will be more significant alterations of the output.

The PCB is layed out for Eurorack style systems only with PCB mounted jacks.
