Up for sale I have a Plinius SA-250 MKIII Class A Amplifier Silver FULLY RESTORED 10/23. This amp was fully restored by Ralph of Plinius Audio Repair (the BEST in the country to restore Plinius amps) and a list of what was down will be listed below. Invoice will be pictured. This amp will deliver 250 WPC RMS @ 8 OHMS and a put double that into 4 Ohms. That is in PURE CLASS A. The unit is switchable to class A/B at the flick of a switch. A ground lift switch was added in the back. See list below for full work performed on the amp. An Amp like this today would cost easily 20k+. Plinius IMO is the much better sounding, more musical Krell. Sale includes ORIGINAL wooden shipping crate. This is a VERY serious and high end amp that will drive most any ever made. Plinius amps are known for driving the most pigish loads.
