Greetings

Perusing he Hammond replacement transformers for guitar amps, specifically the Super Reverb and the Bassman, I find that the 290D2X is listed as a suitable PT for both. This is rated at 300mA for the plate winding, just as you mention above. Might this be the device in question?

You also mention an OT of 6k6 in the first post, but a correction of 4k as the Bassman OT. Even though the Bassman OT would be "wrong" in a Super or bandmaster, it seems compatible with at least the Hammond PT clone.
