The ThivanLabs Ultimate 300 Preamp is built as a single-stroke tube preamp based on the famous 300B vacuum triodes. One of the main features of the model is the built-in support for vinyl record players: the novelty is equipped with phono correctors not only for traditional MM/MC heads, but also for optical cartridges. Matching via a step-up transformer is provided for MC cartridges.
