Also note, the PM-660 runs very warm, even just idling. That's normal. She's a big, powerful amplifier and likes plenty of ventilation. Don't go stacking stuff on top.
It's phenomenally powerful into low impedances and also has a large transient capability. Consider its rating is a conservative 80wpc. It easily surpasses 120wpc continuous into 8R and nearly double that into 4R both channels driven. You will blow the fuses before you blow the amplifier.
Indeed. I've been leaving it on today to burn it in and get the caps up to speed. It's sounding better and better. I'm running through some Altec 604Cs which are 16R and it's putting out 105-110db @1M with he volume knob <5. It is cooking. It's 30* outside and I have a fire going all day to. Not sure which is keeping me warmer. Thanks for your help. Elvis thanks you too! He hasn't sounded this good in years.
