Note the size compared to the nickle.

"ARP 4075 Resonant Analog Filter PCB assembly

Original ARP circuit board assembly pulled from a working OMNI many years ago. This is the same board which was featured in many ARP classic synthesizer designs, including the 2600, Odyssey, AXXE and others. With just a few additional components this could PCB could make an great addition to a DIY modular synthesizer, replacement for a bunk potted 2600 filter module, or even a standalone effect unit. The board requires the standard (bipolar) +/-15 Volt power supply and a few resistors, pots, and trimmers to be used as a standalone device. The board features several long pins which allow it to mate with another board (on which the pots, etc may be mounted), making it easy to work with."

    It should be noted that this is not the Moog-clone filter; it's the "post-lawsuit" filter.
