Demmit. My HT5 head has the low volume issue. Don't know if it's the power tube because its not available sa Lyric. Swapped out the preamp tubes pero ganun pa rin. Sprayed contact cleaner on the external holes on the amp. Nada.
Rant 1. Doesn't make sense that Lyric doesn't carry the power tubes. Para kang nag benta ng BMW na wala kang replacement parts.
Called the Lyric main office, talked to a 'Mico' from marketing. Sabi sakin they will inform blackstar. Another 'scratch head' moment.
Rant 2. For such and expensive amp - quality issues. sus. All over the internet. (no more warranty tong akin).
sucks.
