I have a friend who's father was a ham he past away years ago and he has some stuff he just came accross and one item is a alpha 87a amp. Would it be worth buying this amp from him for use on 11 meters with my rci 2990 and if I did would I need to get anything done to have it run up to par. I seen that its rated at 1.5kw would i be seeing that on 11 meters am/ssb?
