Op-amps are an interesting and vital part of electronics as we know it; however, op-amps are typically very sensitive and frail (with respect to amperage/voltage limits). I was thinking more along the lines of gas/plasma tubes, which, on the low end, could be a common fluorescent light bulb (albeit one with modified current limitation circuitry), to large radio (and other types) of gas/discharge tubes on the high end... But, that being said, there's certainly nothing wrong with op-amps...
