•
Correct resistor placement, "that's not a 10K where a 1K should be,
is it?"
•
Proper power source of 12 to 15 volts DC, check this by actually
measuring the power source's voltage while it is connected and
powering your TV6.
•
Proper video and audio from your source, be it a VCR or other.
•
Correct placement of disc capacitors. Make sure the .001 uf values
are not confused with other capacitors.
•
All solder connections.
As a general rule, frequency drift or hum in the audio is caused by a poorly
regulated power source and erratic or intermittent operation from faulty
solder joints or cable connections.
If you're having trouble getting your TV6 to tune to channel 6 you may want
to try changing C7 and C9 to 27 pf capacitors. The change may affect your
ability to tune channel 3 but will move the range up so that you can tune
channel 6.
