Yes.  Those are pretty much the same as the LS series, but more compact  in 
physical size.  There as also the "O" series, which are ultra-miniature high 
fidelity units.   Not quite so good as the LS and HA series, but pretty 
close, especially considering the size.  The O series are not very well 
magnetically shielded, however.

I have seen transformers in pre-WWII broadcast quipment that looked exactly 
like the HA series except  they were black wrinkle finished, but they 
carried the LS number.
