I would imagine such a device if it exists would be quite expensive, and quite expensive to make, but I would have thought it technically possible to make. _______________________________________________ volt-nuts mailing list -- [email protected] To unsubscribe, go to http://lists.febo.com/mailman/listinfo/volt-nuts_lists.febo.com and follow the instructions there.
