Can anyone tell me the age of Rotel amps?


Can anyone tell me the age of Rotel amps?
I know the older ones had colored speaker connections and the newer ones have clear connectors.
When did they start with the clear connectors?
Thank you.

Do you have a model number of the Rotel amp you want to know the year it came out?
Or just Google Rotel Amp and click on Images and the top to see all the Rotel amps over the years.
That why you should know what amp your talking about and get the model number.
