Yes I noticed that same thing on mine tuned close to 3 the voltage is at 33 v but move it the other way and it will drop to 15 or so volts . Maybe this is how it was designed I don't know but I wish I could get a pic on mine by finding what's wrong. The thread I read from England said the same thing and he thought that the varicaps were bad, I have no clue even where they are , possibly in the tuner it's self being the 33 v goes directly to the tuner fed by the video- IF board and dropped down from 45volts via a 120k resistor and the end pin2 next to the -33 v output should show - 0-33 v negative as the tuning is moved , it's marked variable in the half ass schematic which don't give any electrical info at all.
