Отлично визуално и добро техническо състояние. Тунера има много качествен звук, но работи със следните забележки:
- не работи в режим автоматична настройка (търсене на програми)
- при вкючване на антена не показва входно ниво на сигнала
- звукът се появява при включен надпис на дисплея "моно". Надписа "моно" се включва с най-долния десен бутон MPX MODE
