An SB-200 or SB-220, and most of the components in my old Alpha will resist transient pulses to a greater degree as compared to a solid-state amp. By their inherent high-voltage design, tubes are not nearly as susceptible to damage. It won't take a direct strike, only a nearby induced one coming in via commercial power or via the antenna system, to take out a solid-state PA without a ccommercial-grade grounding and bonding system. If you cannot see this, I cannot help you. This is not to say that I will never own an SSPA. It only means that my station will meet Motorola's R56 -- Standards and Guidelines for Communication Sites, before I go down that road. My station will far exceed NEC Code... BTW, I work as an 800 MHz trunking system manager, and have had direct strike damage at a new comm site TWICE this summer because of an improperly installed new site grounding system (the site has a lightning-attractive 250-foot freestanding tower). The site's ground, measured at the bonding conductor exiting the ground from the building's ground ring and bonding 4 feet away to the building's AC entrance panel Neutral leg, was 8.9 ohms. This is NOT low enough, given the damage to equipment inside the building -- both times. This is being corrected! And yes, the separate tower and building grounding rings are below-grade bonded by 2 each, 2 AWG cables, to include bonding to the site's generator, fencing, etc.
