While anxiously awaiting the arrival of my amp, I`ve been looking into an output protection circuit. There a many available on Ebay that look pretty interesting for very few dollars (10-25) obviously of Chinese origin, a Velleman kit for about $40 and this http://home.earthlink.net/~dimlay/id24.html for $100 or so. I`m really liking the last offering as it is PL specific and mounts internally with no chassis modification and reversible if so desired. Anyone care to comment on these or perhaps suggest another option? TIA
