For the yoke.......
Loosen the clamp.
Push all the way forward against the "bell" of the CRT.
Get a picture on & be sure its not tilted.
If its tilted rotate yoke a little bit. Use a glove or just be careful of
the wires. It wont kill you but you can get a surprise !
Slowly tighten clamp until you can JUST not move it. Done
For tuner.......
Pull tuner assy.
Remove the tuner shield. It has catches on both sides & slides off. It
is U shaped.
You will see 4 or 5 wafers that the shaft go through.
Spray a little contact cleaner or WD40 on the wafer part that moves.
Spin channel knob about 4 rotations each way.
Try it, should be clean now.
Other stuff.....
One pix shows hoz way off. Odds are the horz hold control is also dirty.
Spray cleaner into the gap where the 3 wires / pins enter.
Adjust back & forth a bunch then adjust to get a pix.
enuf fer now. I need an ale
