Notes

PrimaLuna's EVO 400 is a high-end tube integrated amplifier typically owned by enthusiasts who expect long service life with routine maintenance. The most common "failures" are consumables: power and preamp tubes wear out and can cause noise, distortion, or channel imbalance.

Heat and vibration can also stress solder joints, tube sockets, and bias components over time. Repairs usually make sense because the chassis, transformers, and build quality are the expensive parts; replacing tubes, a relay, or a capacitor bank is often cost-effective versus replacing the whole unit.

Replacement becomes more reasonable if an output transformer fails, there is repeated overheating damage, or the amp has suffered major liquid intrusion. Factor in tube replacement cadence when comparing repair quotes to the threshold.
