I don't own one but google can find several links to forum threads asking about how to repair them, eg

http://www.diyaudio.com/forums/solid-state/251523-marantz-pm-64-mk2-missing-factory-caps.html

This thread mentions that 100 euros was on the high side of what to pay for this amp in 2014. Consequently if you do consider having your amp repaired, then be careful of the cost, because it could be cheaper to buy a replacement PM64 for say £60.

At least you know that the capacitors in the power supply are probably ok, because your amp powers up.

Clicking sounds are often caused by relay switches - sometimes used to disconnect the power amplifier outputs, when the amp is first switched on, and the voltages in the various amplifier stages are stabilising - this does protect the speakers from voltage surges and subsequent damage.

My first guess is that one of the relays has failed, and it could be relatively easy to replace.

There do seem to be plenty of web links for this amp, so I think it must have been relatively popular and well liked, and the diy hifi threads do seem to be populated by enthusiasts familiar with this amp - so don't despair because i think someone will be able to help you.
