Yes - usually. > There is no audio amp in the > chassis either. Does it use one from a VHF or UHF Mobile?? Most of the audio amp is on the A&S Board, but the pass transistor (power amplifier) assembly is on a hunk of aluminum, and yes this assembly (TLN4290B) can be stolen from a mobile and used in the station. The hunk of aluminum is anodized (coated). The anodizing doesn't conduct electricity. This allows the transistors to be assembled to the heatsink without an insulating washer. While you don't need to remove the transistors for remounting the assembly into the station, you should be careful with it as not to scratch this coating off when handling it. Kevin Custer
