Tuning Eye Help
#14

Jamie, keep in mind that the eye tube acts a signal strength meter, not an absolute tuning indicator, so only the strongest stations should close the eye. If you make it too sensitive, the pattern will overlap and you loose the ability to use it as a tuning aid.

The 6U5/6G5 was specifically designed with a extended cutoff grid, so the pattern would not close or overlap on strong signals. You can make the tuning action somewhat more sensitive by removing the 8 meg resistor R22 and leaving it out or replacing it with the 22 meg that you previously installed.
