    Penta Lab One - humming and thumps on starting up and shutting down

    I have three questions if anyone can help me please....

    One of my Penta Lab Ones 6602 serial number 05207700 (- the tall hexagon ones with built in active power amps at the bottom) has started humming all the time that it is playing music, it also thumps on start up and has to be put to sleep manually with the switch on the front...what has gone wrong?  Can it be repaired?

    The Speaker A outputs on my B&O 9000 Centre (CD/Tape/Radio/Amp)don't work anymore but the Speaker B ones do.  So I have used the B socket.  is this a problem?  Can it be repaired?

    My remote control for the 9000 does not work - do they suffer from dry joints?

    I love my B&O and can't afford to replace it plus I prefer my current system to the new stuff - if I could get it working fully again!  Any help would be appreciated. 

    Many thanksSmile

    The humming and thumps sound like the power capacitors may be dying, and the power supply may be leaking AC hum onto the main amplifier supply voltage.
