Hello, need help please!!!

I have no electronic background and in process of finding speaker for my RCA Victor 19k since my speaker and output transformer that located on speaker are missing.

I do not know what other RCA speaker fit this radio in-case cannot find RL-70J1 speaker. My understanding is that output transformer to match push-pull 6F6 tubes.

Schematic indicates speaker is RL-70J1 and output transformer is located on speaker. Not sure if primary or secondary is 650 ohms, voice coil V.C. Impedance is 2.2 ohms and part number 33444.

This a the link for schematic:

This is the link for part numbers:

This is the link for Data:

This is the picture of what I fund on internet.

Thank you very much!
JZ

ARF rules prohibit starting multiple discussion topics about the same thing, and this has no place in Vintage Audio.
