I'll give you props on any kid your age for trying to explain things in an AA5 radio! 4 out of 5 stars. One messed up thing I caught was (at 6:16 in ) you said those tubes had multiple plates , instead you should have said multiple grids. Another important point when it comes to metal dial faces and metal pointers. There should be a thick fiber washer on the shaft to keep the pointer from making contact with the metal dial face. The tuning capacitor is always at chassis ground and the B- is floating and the two should never directly meet!
Next task, start reverse engineering how this stuff was designed. I started in my high school years on transistor TRF, regenerative, and 5 transistor superhet radios. Imagining the operation of pentagrid converters will keep you busy a while.

Brother.. you did very well.. informative..... peace out from TX.
Well done. I admire your enthusiasm. I wish there were more of the younger generation taking up an interest in vintage technology.

I think he was talking specifically about the 12SQ7 (Dual-Diode Triode) which I am pretty sure does have multiple plates and only one grid.
I have a few of these AA5 sets, a six tube set, and just picked up a seven tube Firestone Air Chief radio that surprisingly still works.
Great job very interesting.
GREAT VIDEO!!!!
