Re: [Amps] 8877 Grid Connection DC or Not

Hi Jim,
   Why not leave the grid grounded but, just measure the cathode and plate 
currents then subtract to calculate the grid current?

 Has anyone run the grid of an 8877
 not connected to ground as far as DC is concerned? 
 
 I really need to meter the grid current by bypassing the
 grid to ground with capacitors and several 10 ohm resistors
 in order to meter grid current. Metering grid current by the
 CT of the filament transformer, and the – of the power
 supply cant be done. Because the power supply – is
 directly grounded.
 
 Anyone had luck doing this?
 
 Thanks 73
