Can't believe Keith Herron would compromise and put an on-off switch on his unit, but guess it does use fire bottles :-)....We just have two power cords on our unit, one for each supply....There is no switch like no switch especially in or across the signal path.....Best handled by either gold pin sockets for resistive and perhaps capacitive loads or soldering them in....Bengal Lancers!
