Mark To answer your question about commercial gear and no equalizing caps, take a look at the schematic of the little Heathkit AT-1 xmtr from the 50s. I Just happen to be renovating one this week and the first section of the cap input filter (two 8 mfd/350v in series) has no equalization. The little rig also has no fuse! Well, probably not the best example of "commercial" equip.
