      FWIW the RCA tube handbooks or other tube handbooks 
will give you the plate load resistance value.  You can 
compare the operating voltages given by the handbook with 
those in the receiver but generally the conditions will be 
similar.  The HQ-120-X through 140-X used the same 6V6 
output stage so the transformer specs should be pretty much 
the same.  I don't have the 150 book in my file but if it 
used either a 6V6 or a 6AQ5 it will also be about the same. 
If it has some other tube look it up to see what the 
required load is.
