.. About the only other thing I can add to what has been written is a couple of small value capacitors from each end of the heater to signal common,and of course keep all lead lengths as short as possible.oh yeah, also..
With ferrite on grid I've found if you cut the actual pin in half, you can slide the bead over the (half) pin itself and still have enough to solder to.
Mount to metal plate, ground plate, investigate tube shields.
Took me a while with D3a but worth it.
