    I really doubt that a power tube in a preamp is going to get near as hot as it would in a power amplifier output stage.

    What matters here is not how hot the tubes get but extending the life of, what are now expensive, tubes by removing what heat they do produce from the surface of the glass.

    I’d prefer to never have to purchase another tube. IERC covers may be the way to do so and if I can’t get those I’ll find others that are similar.
