[R-390] Tracking down low sensitivity 0 to 8 mhz problem

[Jordan Arndt]

Hi again group...

While replacing C327 with a mica cap did bring the 1st Xtal Osc output up to 
snuff, I still find problems below 8Mhz, so I have a few questions for those 
in the know.

The service manual states that E402 should show from -4 to -11V when 
measured with a USM-116 VTVM which has a 100 Megohm input impedance on DC.

What do you guys use to measure this voltage..?

What type of tip/connector etc. do you guys use to insert into E402, E209 
etc..? Is there a standard "pin" that fits snugly in those connections...? I 
do have and use the specified CX-1363/U Test Lead, but I cut the alligator 
clip off the positive lead due to it's size and the tightness of the 
available space around the test points.

Lastly, for now at least, Do you all follow the manual instructions for 
aligning the 1st and 2nd IF, or do you use your own methodology...?

Thanks for your time and any possible responses...
