Produced in the late 80's if i remember right. And HIGHLY underrated. These are what really put RF on the map imo. Highly sought after back in the day for its small size and high power. Hence the nickname, "the cheater amp." You could hide mount this little guy and not tell anyone it was there, then blow eardrums with it. Great piece!!! As for value, not really sure. Not many left nowadays. The ones that are left are being held onto. Find an old RF Punch junkie and you might have a buyer. Or use it, you might be surprised at its power.
