Exact same as in 66, same arrangement too. Yes 10mA. According to what I remember when I calculated the current, it was a bit marginal, and since his is not the first choke I see burnt in this same place I think Philco cut corners on this one a bit rating it marginally.
Now a typical output transformer will likely be rated a bit better current-wise but then it can have lower inductance and surely lower DC resistance. DC resistance is not as important as it is still small compared to the resistors in series with it.
It might work just fine. Especially considering a 6uF cap after it.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
