Hi Ed,
Congrats!! It is precisely the 130V V and 8" speaker that makes the set sound good. Sets with a tube half wave rectifier only put out between 90 and 110V to the output tube plate. Between 120V from the utility and replacing the selenium rectifier with a silicon diode, you can squeeze much more out of it.
Philco made several "table" sets in the late 1940s and early 1950s (actual tables) with AM - Phono chassis. These sets used an 8" speaker and a full wave voltage doubler rectifier. The 49-1606 AM FM Phono Console puts 195V on a 50C6 Output tube (Beam power), yielding 5W. This is about as much as you can get out of a 35L6 or similar AA5 Output tube.
