WHISKEY 1446 4
in this pic you can see one of the relays and the keying circuit board beside it. The keying circuit board has a real glare off it so its hard to see. The keying circuit is to the left of the relay. Behind the keying circuit more to the left you can see a small piece of the LED driver circuit. This is the circuit that makes the modulation bar graph work. Just to the left of the keying circuit is the adjustment pot for the LED display. Its fully adjustable. The bar graph can display input or output power/modulation. The circuit is based around a DBL1016 led driver IC.
To the right of the relay is a second relay for the pre amp circuit. Its located right beside the main relay and is black. The relay is smaller in size but has the same current rating as the larger one.
Behind this second relay is the main power input board. The incoming power into the amp first goes to this board then to different section of the amp. The board is basically a rectifier diode and couple of caps
