You will love it!
I have an excellent condition 727 exactly like my Dad bought new back in '72.
I had to do alot of cleaning, deoxiting, and bulb replacements, and tweaking with FM alignment, but it was basically fully functional. It is in my living room now along with a Dual 1219. The blue analog dial background is so beautiful!
Sometimes I'll plug in my Ipod in with a 70's mix, play it through the tape monitor, tuned to an FM station (position) that I used to listen to as a kid at 104 MHZ (it's country format now). That way all the lights, indicators, and meters look exactly like a step back in time! I know I need a life! But my wife thinks it's cool!
My 727 is very warm sounding, along with ample power. With the 828 being a step up, I can only imagine!
Enjoy!!
