Start of data used in restoration of McMichael Twin Supervox - U.K. circa 1933
This is the paper label mounted on the back of the Magnavox brand speakers used in my Twin Supervox.  Click on this Icon to download a recreated .pdf file that you can laser print onto silver paper.
NOTE: The inside diameter is really too small to fit properly on the back of the speaker.  BUT that is the way they did it and I see no reason to change the fact.  It helps to explain why one had popped off and this one was just barely attached at all.  Also note that the paper alignment in the die cut is off center.

NOTE: The model number is punched in the paper with 1/8" punches.  In this case 144.   There is a curious upside down C punched between the Model No. and OHMS. fields.  The number 1500 is in the OHMS. field.

Use an air brush to spray on lacquer tinted with a few drops of analine 'light oak' wood dye to give your reproduction a slight aged look.
Ugly mains transformer.
The mains transformer looked terrible. I was able to peel off the outside layers of insulation paper and recreate what was there. I got lucky in that I've had for nearly 40 years some of the old style Kraft paper with water soluble glue that used to be used in xfmr winding. What I did not have was any transformer varnish. The new stuff has a red dye in it. Did not want to go there.... Found out that the local auto parts store has spray cans of a transparent coating that is supposed to withstand up to 500 F. So I applied that to the dried kraft paper. THEN to get the original look, I figured out that I could use a little PVA veneer glue with transparent amber dye as an over coat. It dries to a great looking translucent effect. It is not going to discolor at normal operating temperatures.
