Concept 5.5 Vintage Hi-Fi Receiver 1975-78 Silver Face

This Concept 5.5 was one of many in line of receivers by Pacific Audio's house brand Concept.  These Concept stereos are made like tanks and sound great.  I've looked high and low on the internet trying to find a full list of specs, but can't. 

This is what I have found:

RMS Power (IHF): 2x55 watts @ 8ohms 20-20,000Hz
Distortion: 0.1% (Full Load)
Input sensitivity: Phono MM: 1.9mV  -KOhm
Phono RIAA: +/- 0.2 dB 30-15,000 Hz
Weight: 35lbs

!!DISCLAIMER!!
This is a vintage unit. This has been tested and is
100% functional. This goes for all vintage equipment. Capacitors and
transistors in this unit are 30 years old. There is always a chance that
these fragile pieces can get damaged in shipping and may need
servicing. Please note that I'm stating these facts because these things
can happen and do happen; not that this unit "will" ship damaged.
