It was something I overlooked during both design and build process.
I initially thought the Hammond OPT just sucked that bad until Jack at Electrprint said to check my gain stage. I studied many IT schematics and 90% of them show the IT connections wrong, is this just lack of knowledge or is bifilar not that popular?

I connected it wrong at first too.... sounded pretty awful, no highs.
At some point somebody told me to switch the secondary windings round, and suddenly it sounded normal again. But as I said, I use it as a plate choke - I've read that elsewhere as well.
Mine sounded like someone adjusted the treble knob from 12oclock to 8
Probably sounds better as a plate choke, I have a nicer magnequest choke that performs better. I liked the control better on the IT transformer even though highs were rolled off.
I'm assuming the shunt capacitance acted as a 6db per octave filter.
Wonder if there's a way to calculated this without measuring?I have a Monoloth magnetics IT wound and gapped for the 300b driver if it ever ships.....
