Hey Guys  got a Problem    

Got the Titan hooked up and seems to be  working fine except for one thing. I 
get full output power good plate current.  But the grid current deflects when 
I talk on SSB  But Idle current seems  to be fine.

The Titan uses a pair of 3CX800A7 tubes in GG.  There will be no grid  
current when idling, when you speak you should get positive grid current.   If your 
meter deflects negative, I think you will find that your grid meter  shunt 
resistor is opened.  It should be a small value resistor in the  tenths of an 
ohm, if you isolate that resistor and measure it, you will probably  find out it 
may be opened.  Try that first.  If anything else was  wrong, the amp would 
probably not operate normally.  73  louie
