Its not so hard to find with the back off, all you need is a plastic rod or wooden spoon etc , take the back off and run the set. Now this is in the scan section tube or tube base but hope for the scan section. When its chirping put a bit of pressure on any coil you see with your push stick. Now do not use too much pressure as its quite easy to shove something and slightly bend the board so causing the faulty coil which you are not on to stop whistling. Another trick to test if its tube heaters etc is use a screwdriver, handle to your ear and blade to tube neck, You got to take care not to slip though.
