Default HP 5245L Counter Oscillator adjust?

Scott,
Those capacitors inside the plugin bay are medium and fine frequency
adjustments. If the coarse frequency adjustment inside the oven won't get
it on frequency, then the others certainly won't have enough range to get it
right.
As I and others have suggested, you really need to verify whether the oven
is being heated before you do any more adjusting. Set the coarse tuning
back to its starting position and troubleshoot the oven circuitry. I'm
convinced that's where you'll find the trouble.
Get your voltmeter out and check the oven heater connection. It will tell
you a lot.


Yup...I will delve into the oven circuitry when I get a chance...have a
couple other higher priority projects to clean up first...
