You may find it's a bit low on HT current raring for much of an audio amplifier. The receiver it's from used a lot of valves, taking a lot of heater current, but the majority of them were running at very low anode currents, and there was just a single-ended 6V6 taking more than a few milliamps.

Also, they had a bit of a reputation for burning out in the original receiver if a fault put the HT demand up at all... and that's why Ed's rewound some at various times.
