Hi,
    Does someone have a readable schematic for the voltages for the grid 
of V2 (6AU6 - 1st mixer).  My schematic and my manual is hard to read 
but I think it states:
-.4 to 0 v Band 1, -.3 to -3. v Band 2 & 4, and -2 to -5 v Band 3.  I'd 
like confirmation.  The cathode reads 1.9 v and the schematic calls out 
3 v.  Is that too much of a difference?  The tube seems to be cut off 
(no signal through it).  I've switched tubes with no success.
