And, no, I did not cut out a hole in the front panel. The steel is pretty thick and doesn't nibble readily. If I need to convert the supply back to "sorta stock" there are fewer/smaller holes to plug. Also, don't get nervous about the meter showing 14.01 volts. It reads a little high. The adjustment pot on the regulator board was set to 13.9 VDC whuich is a good compromise for running test radios and topping off my gel cells.
