when i was a teen in roanoke rapids NC back in the latter 70,s Mr. Clean was one of the local smoke blowers . he had a cobra 139xlr (with a D104) , a 10 tube (i think) elkin amp going into a superscanner about 40 or 50 feet in the air and he sounded fantastic ! . he replaced the cobra with the CPI 2000 and he had the seperate CPI preamp with it . he sounded as good as ever as best as i can recall 30 years later . he kept using the CPI , i dont recall if he sold or kept the cobra , but i didnt see it on his desk anymore when i went over there . another MR. clean (in lil washington NC) used to set our stuff up for us ........ those were the days
not a pretty as a 2000 IMO , but definately can be as good . id be tickled to have either !
congrats on a nice find !!!
