Believe it or not, I still haven't heard that Sony I've fixed. Spectrum analyzer is really fantastic. Whole unit is with micro-switches, and everything controllable via remote too, works perfectly. I did connect some small speakers briefly just to check if there is output, but I don't have those speakers with flat cable that go with FH-150R yet, and I've given up search, till I feel better.
Thanks once more for kind words to all of you.
