LL1660S Anomaly

K&K Audio / Lundahl Transformers

Welcome! Need support, you got it. Or share youe ideas and experiences.

I was working on my new push pull amp with 6SN7 || -> LL1660S -> EL34 x 2
The 1660S is configured as ALT-B (SE to PP out). When I looked at the scope this is what I saw.
There is considerable ringing on the 1kHz square wave. This output is taken from the plate of the 6SN7.
The 6SN7 is running off 200V B+ and 750R cathode resistor, bypassed.
Substituting two green LEDs did not improve the output.
Any thoughts or suggestions as why this is happening?
