Zenith c730 restoration help...

[Sancho]

Hello,
I bought a c730 for pennies on the dollar at a local thrift store and to my suprise it worked immeadiatly after powering it up. I plan on stripping it and re-veneering the box, however, is there any good way to clean the faceplate? what about speaker replacement, this one has a ripped woofer cone. Is there a good paint to use to re finish the knobs? All in all the reception is awesome, Im shocked someone would toss this out... Lastly, does someone have the schematic for this little guy?
