I too have heard they are the best of the best. I'm sure I will enjoy them and keep them going by changing the E Caps....Thanks again for all the info...I hope you enjoy your 2 CPI 2000's as much as I enjoy my 2. Arguably, the best "legal" FCC type accepted CB ever made and that includes Browning, Tram, Stoner, ARF, SBE, Uniden (Although I do love the UPD-858 deluxe SSB chassis), etc.
Having said that, they are pushing 45 years old and even though only the best available components were used in them, the E Caps should be replaced. It is a PITA because they use a double sided circuit board, but use some quality low ESR caps (Panasonic, Nichicon, etc.) and the radio will still be working 40 years from now.
Good Luck.
