Hi, guys!
I'm working on a hybrid headphone amp with TPA6120 and AD1865 as DAC. I want to place cathode follower circuit between them, but I'm consirned about possible damage from the tube power supply +-140v. I'm providing schematic. Can someone with more experience in such a type of circuits give some advices. Thank you!

You have protection diodes in there, so as long as C12 is rated for more than 140V you will be fine.
Thank you, Merlinb. I was not sure that the diode protection is enough. What about the AD1865? Is there any situation that damage may occur?
