Is there an advantage to either? Can using 2 100-ohm resistors @ the power lamp REALLY save transformers in the case of a power tube completely shorting? I'm looking at an early SF Showman (still ab763) that had the power trans replaced somewhere along the line. Apparently the original Silverface PT didn't have a center tap, because there are still 2 100-ohm resistors on the pilot light- connected. So right now BOTH the center tap & the 2 resistors are hooked up, and the 2 resistors are fried. I'm debating whether to use the center tap of the replacement PT and take the old resistors out, or disconnect the center tap and replace the 2 resistors.
