Philco 37-670B
#30

So it was time to remove the RF unit. Again.

First, we remove the dial scale. Use some needle nose pliers and put the jaws through the two holes of the metal disk which holds the dial scale in place. Twist counter-clockwise, then remove the disk and the dial scale.

It is easier to remove the dial scale if you first remove the shadow mask arm from the band switch shaft. Photo to follow.

Next up is the metal and phenolic piece behind the dial scale, with the glass rod in the middle. This is what produces the fine line in the dial scale which is the indicator.

Remove one bolt on either side of this piece, then remove the piece.

Now let's remove the shadow mask arm from the band switch shaft. One set screw holds it in place.

The metal piece which holds the dial scale in place must also be removed. This is also held on with one set screw.

Also remove the felt washer behind it. Now, remove the shadow mask. You are left with this:

Remove two bolts and remove this piece.
