In 1968 I purchased a used HK Citation. As you may know few amps ran the output tubes any harder or had higher under chassis temperatures than a Citation II. Seeing the handwriting on the wall for tube availability in 1974 I replaced the output tubes. When I did a McShane rebuild about a dozen years ago, every resistor and capacitor was still original. This amp had literally several thousand on/off cycles. What I think this illustrates is that if one picks the correct parts for the duty and environment where they are used. a solid state rectifier does not place life shorting stress on amplifier parts. That said an inrush current limiter make sense to increase the safety margin for components and allow a smaller power fuse for quicker protection against excessive current draw.
