Monday, February 19, 2018. The FPB 300 right channel now seems to overheat at low playback levels regardless of input or speaker connected. One time in January it reached 207F before I shut it down. That time it had reached 197F during playback, I shut the music off, and the temp kept rising anyway for ten minutes. Power consumption was about 900W. This looks like at least one malfunction!
