Output transformer from TVK110LM. Modification.
We're making a TVZ from a TVK 110LM.
The modification isn't difficult. It's valid for a 6-ohm load. We wind two secondary coils. We wind a new secondary coil with 78 turns. Then the primary coil again with 200 turns. Then another 78 turns for the secondary coil and 200 turns for the primary coil. We connect the secondary coil in parallel and the primary coil in series. This creates a kind of sectionalization.
Believe me, it performs significantly better than the TVZ 1-9 coil without any modifications. I've used it with 6F5P, 6F3P, and 6P14P tubes.
