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.
