[Amps] 6146 AM Modulation

[Radio WC6W via Amps]

 As part of a curious Amplifer project I'm seeking the proper percentage of Screen Modulation to achieve 100% Plate Modulation of a 6146.  The Screen will be sourced from an independent supply modulated along with the Plate supply.  

 Some associated data points for other Screen Grid tubes:

  The RCA 4CX250B data sheet states 55%.

  The Eimac 4-400A data sheet shows 70%.

  The Eimac Care & Feeding book says a range of 70-100%.

  The Orr Handbook indicates 60% as a starting point. 

  And several references suggest that it should be disclosed on the manufacturers data sheet.   Yet, nothing I have seen defines the number for the 6146 ...

  Anyone know the answer?  

73 & Good morning,
