    If the caps are gone you will notice at higher volumes, a harsh and ragged sound will ensue.
    Leaving alone Neil, the condition of this amp is just beyond belief, someone must have a time machine.

    I bet it's a cracking amp though. what's the phono stage like?

    I wish I could tell you Steve but I no longer use vinyl ( ‘‘twas a comprise with the wife ) , reviews suggest its very good though.
    I’ve fallen in love with it now, the vu’s are quite mesmerising too.
    Now the other dilemma is the amazing Pm4 🤷🏼*♂️

    I had similar black Nippon Chemicon caps in pristine condition on my 40 y.o. Hitachi Amp which I bought with the main goal of learning how to recap. The caps look like they just left the factory, however SQ jumped into another league after I replaced them with modern audio quality Nichicon caps. Point is, caps might dry out without showing any signs.

    As for the recapping, it's a quite a simple process, just solder the old capacitor out and solder the new one in . What was unexpectedly challenging for me was removing and reassembling the PCBs to get a good access to the capacitors. It was a proper nightmare for me, but may be your amp is easier to work on.

    I've recapped many receivers and amps now and I would avoid the temptation to fiddle, it's Pandora's Box.

    My Quad 405 is more like Trigger's Broom, think there's only a few original resistors left!

    Having taken a peak inside I decided definitely not to touch this one
