[AMPS] Alpha 374 cathode circuit

[nospam4me@juno.com]

Hello there, 

The Alpha 374 boasts three 8874 tubes in grounded grid.   RF is 
cap coupled to the three tube cathodes through a toroid xmfr, the 
secondary "swamp'd" in parallel with a high wattage 100 ohm 
resistor.  
Can anyone provide the ratio of the toroid..   and or the approx 
value of one, two or three 8874's in grounded grid..?  

thanks

ps  I have the owners/service manual, the ration is not indicated 
in the book.
