OK, start eregretting a little purchasing this radio.
Now, I started pulling tubes out, and the last tube I pulled was audio amp and something drew my attention....the screws. The screws held the panel. The panel is off-center. OK. Looking at the tube - type 26. The output of the 70 is always 47 (pentode) and the 26 is triode.

The filamet of 26 is 1.5V (47's is 2.5V) and I do not see a resistor or anything to buck it.

And then....why?
