Just a short post while I am repairing/restoring an absolutely massive Marantz PM-8 integrated amplifier.
These main filter capacitors in the Marantz PM-8 sit in the power supply and do all the ‘heavy lifting’ required to make the power supply smooth and quiet. All four 15,000uF capacitors have literally spewed their contents all over the insides of this beautiful amplifier.
Repairing the Marantz PM-8 involves removing these dead capacitors, cleaning the chassis and installing new parts. I’m using higher capacity, higher spec Illinois Capacitor (IC) parts in place of these original Matsushita caps. It’s astonishing that this amplifier was even working with this level of damage to the power supply!
