Hi, I have a rci2970n2 I wanted to check the driver and final bias to make sure it is set right.I don't have a DC Ammeter Could i use a dc volt meter to check the bias? I have a dc amp setting. But nothing shows up. Also the main pcb is a ept-695015a Is that board used in any other radio? I want to do a alignment but there is no service manual for the radio. I have read some scary post about the irf520 mosfets in this radio and want to make sure the wattage and bias is right. The main board in the galaxy 98vhp is not the same as the rci2970n2.
