Hi Dave,
A few things come to mind. Open volume control. To check disconnect and use an analog ohm meter connected to the center post and one of the ends. Set meter to it's highest scale. Needle of the meter should move nice and smooth. If needle jumps around you need a new pot.
Tube shields in place??
Could the previous recap job has issues. Wrong value cap in the wrong place or wire placement after recap could be causing your set to oscillate.

CTC-25 Glutton for punishment!!!!! My parents had a CTC-7 when I was a kid back in '59. Used it till the early 70's when they got a Sony Trinatron.
