Default KT33 Push Pull

Hi all,

I recently picked up a quad of NOS GEC KT33C's and I was looking to build a low power, all-octal AB1 PP amp around them.

I have a pair of 4k3 UL OPT's I can use, which are close enough to the 4K the datasheet recommends.

Does anyone have any experience with these?
There doesn't seem to be much info around on them.

This transformer should work since impedance point of view, but check that wires supports current flowing in the windings, and that core will not saturate with the voltage difference between plate and plate at full plate voltage excursion.

Good luck.
