Interesting indeed. Philco's TVs have a weird lineup too including loktals.
Here's what Reece had to say before my thread was "purged":
Quote:
On various tube lineups: right after The War consumer demand was high and manufacturers couldn't make radios fast enough. Sometimes in mid-stream they subbed equivalent tubes according to what was available and what they could buy. Sometimes you'll see a mix of three or more types of tubes, octal, loctal, large pin, or miniature.
