if you look close, it has an rf preamp before the converter, the converter is hiding behind an if can
So it's sk, sa, sk, sq, then 50L6 and 35z5
But look for a tube location chart on the cabinet, or use the one on nostalgia air

If it has the tubes I think it has, the 12SA7 goes at the end next to the tuning capacitor. The next one, on the other side of the IF can, should be the 12SK7. After that comes the 12SQ7 and then the 50L6GT, with the 35Z5GT close to the panel.
