[R-390] First Xtal osc low voltage

[dog]

I'm finally getting around to checking the Xtal oscilators in the RF 
section. The 390A doesn't exhibit any sensitivity issues. But the first 
xtal osc is only giving me -0.9VDC on E209. Tried a 6AK5, V207, out of 
another RF section as well as a 6C4, V202. Now I don't know about the 
56K or 220K resistors, not sure I want to pull it apart to look. Larry's 
article says not to worry near as I can tell if only one osc is low, but 
this is pretty low from -5.5VDC. The others are E210=-4.2VDC and 
E211=-3.5VDC. Any suggestions other than taking it apart? I've got some 
tube extensions.
