>I have 4 polyfusion LFO's for sale.

>These are origional Polyfusion front panels in conjunction with exact
>circuit board's cloned from a working LFO in my possession. The boards are
>commercially made, double sided with solder mask both sides and silkscreen
>with part designators and values.
>
>The modules are unusual in that they have a waveform reset position control.
>This allows the wave form to be reset with another pulse like hard sync but
>it allows you to set the  point that the waveform restarts from.
>
>At audio rate this provides some unusual sounds.
>
>There are only a handful of these modules in existance as it was a design
>that came late in the polyfusion  production. The panels where left over 
>from old polyfusion inventory

>Specs.
>wavefoms include
>	sine,saw,inverted saw,pulse with width control and triangle.
>All waveforms are availble from separate outputs
>Range Switch for taking frequency into audio range
>Voltage control of freq
>Adjustable waveform start point
>Reset input (hard sync)
>Pulse width control and voltage control input for pwmod
>output swing is plus and minu 2.5V
>This is a high quality design that uses commonly available components.
>
>The cost for an assembled unit that will fit into a standard polyfusion edge
>connector is $450US
>
>I will also be selling unpopulated boards with no front panel of the LFO for
>$50.00 each. plus shipping I have 10 available.
>I will provide assembly documentation and parts list with the boards.
>I can also supply parts for those that need them.

>ALL PARTS INCLUDING SWITCHCRAFT JACKS AND MOUSER POTS (NO KNOBS) $75.00
