Help me to choose the adequate ferrites

Hi all,

you will find enclosed the schematic of my DAC. it consists in 2 tda1541 in // with the output buffer made of two 6C45PI.

I found the schematic of the output buffer in the net.

Unfortunatly, I don't know which ferrite beads I should ordered. :(

The ferrites I'm talking about are L3,L4,L5,L6 (connected to the heater of the tubes)..
They are dedicated to avoid the tube from oscillating.

Do you have a reference, an example of ferrites I could buy ?

I was previously thinking of THESE ITEMS (in french sorry)

Regards

ask the schematic's designer, he'll know what he wanted as a ferrite
I did. unfortunatly, the entended items are no longer availables. And I couldn't rate their equivalents.
