The diodes go between the plates and the filament, you should also use a series resistor that will provide the same or near same voltage drop as the 5R4. no need to do anything with the filament wiring . The resister is probably in the range of 200 Ohms. Probably should use two 1000 V PIV diodes in each leg. if you have an old octal tube base that can be a simple plug in. I think plug in solid state replacements are still available.
