VHF Tuner Alignment: where is the overall oscillator adjustment?

[zeno]

On newer tuners the FT has a set range. Usually if you say
put it on ch 6 you can tune UP to FM radio or DWN to ch 5.
So yours is normal.

Old tuners had 12 screwdriver holes on the front of the TNR and
one FT coil. To adj center coil then adj the channel for best pix.
