Problems with cathodyne

Problems with cathodine

Hi!

I built a driver for PL500. The schema and the pictures of the cathodine signals is in the attachment. The upper side of cathodine has a big distortion :(

I was tried with other tube, but nothing changed.

If I pull out the second ECC85, the two signal is full symmetric.

What's the problem?
