The ANODES go to pins 4 and 5.  Tie the cathodes together and run them to 
either pin 2 or 8.  Depending on how the transmitter is wired, if you remove 
the 5 volt filament transformer, you may need to short pins 2 and 8 
together.

In my Gates BC1-T, I removed the wiring  from the 5R4 socket entirely, and 
mounted the diodes on a separate terminal strip.  That freed up the octal 
socket for a 6AS7G tube that provides protective bias to the 833A stage for 
CW operation.
