i have a amp that i purchased from a guy way back in 1982 it actually has MUD DUCK painted real nice on the cover as well as the name on the knobs. its a really nice cabnet and its a tube unit. DK 750 and swings around 1200 if i remember correctly. i really never new of or saw of another amp called MUD DUCK. the box is 10"x8"x14". it has a switch for ssb/am two hi-low switches a modulation light and three tuning knobs one on the side and two in the front. it is a well made box with a nice ventalated mesh top. could some one tell me if its somthing that was made by DR CBSTIEN in his garage or was manufactured by a company. not working now but would love to get it back up and running been out of service for about 15 years.
