Glad to have found this site. Still using my Carver Receiver 2000, purchased in 1986. Added a second 2000 in the 1980's for the office. Also have a DTL200, TDR2400, a C9 and a PM175 which is used for another application. All of these are working, but long overdue for upgrades which I hope to begin tackling this year. Undoubtedly the Carver site will be invaluable.
