Looks mainly. :laugh: TUNE and LOAD should only be on a tube amplifier and not a tuner. Usually it is labeled INPUT and OUTPUT like Palstar or R-TUNE and X-TUNE like the old Kenwood tuners or even TRANSMITTER MATCH and ANTENNA MATCH like Heath and others but never have I seen TUNE and LOAD on a tuner. They are simply variable capacitors that work together with a coil to create a variable impedance matching device that allows you to compensate for a bad SWR by making your radio see a good match even though you still have a crappy antenna match. Kind of like looking at the world through rose colored glasses. everything is still bad but you just don't see it.
