I have a chance to buy this amp from my local CB repair shop guy because he is upgrading to a 2000 watt unit and he is asking $150.00 for it. Is it worth that kind of money? It has 2 extra cooling fans mounted on top and he says it puts out 600 watts. He used it himself until he upgraded. Also wondering how many Amps it might draw. Have at it! Thanks in advance. Mike
