Lyric S7
#4

Hi Skip,

Sounds like someone wired the power supply wrong. The positive side of the caps should be connected together and the negatives have the speaker field coil between them to provide a voltage drop for the output tube grid bias as well as the speaker field. Maybe the speaker has been replaced with a PM?
