Solid state amps do not require added inrush protection.
And most correctly designed tube amps do not need inrush protection. In cases where the design, usually HB ones, have excessive current capacity in the heater or filament transformer, or in cases where HV transformers have insufficient resistance in the secondary are cases where inrush protection is desired.
Amps such as SB-200, SB-220, TL-922, L4B, Centurion, Titian, Amp Supply, Ameritron, and other like commercial amps have sufficient design implementations such that those do not require inrush protection. At the same time, many amps using indirectly heated cathodes may have time delay systems to allow the heater to get the cathode to correct operating temperature is different than inrush protection
