Randall Amp.

[Len Ryder]

I need some info. I have a Randall Commander Mark IV. It has 4 10" speakers with the #'s 67-7318 on each. I has 200 W on the I.D. plate. Unfortunetly the serial # is almost gone and only the last number (7) is readable. I phoned the Randall people and apparently the Co. was sold and the present Co. say they have no records on older amps. They figured it was probably in the 80's era that it was built. As I want to sell the amp, I'd like to try and find some info on it and app. what it's worth. Any ideas ?????
