Hi folks - Can an Argo user answer two really dumb questions for me please? 1 - Where is the internal speaker located? 2 - How can I guestimate what the power usage would be on 10 watts out put? The specs show power usage for 20 watts. Is it a proportional thing - ie if its 10 watts out the power usage would be halved? Thanks for your help. 73/Tim NZ7C
