[Hallicrafters] SX-62 and R-42 speaker

[Richard Knoppow]

    I'm not surprised. I should have suggested a book shelf speaker when 
you asked. The tubes in the SX-62 are push-pull, not parallel. More 
power out and less distortion. The lack of DC in the core of the output 
transformer, or rather balanced DC, eliminates core saturation and loss 
of low frequencies so receivers with push-pull output usually have good 
bass. There is enough power for a bookshelf system provided you don't 
want to shake the walls with it. The SX-62 is good for maybe 8 watts 
with low distortion. A lot of cheaper home hi-fi amps were about the 
same power.
    I am not sure what kind of speaker is in the R-42 but its a small 
bass-reflex box, probably too small for good bass, the bookshelf one 
will beat it.

I decided to use a bookshelf speaker which I had.  The sound on FM is very good.  I have it in my front room and it looks and sounds good.  Thanks to those who responded. I'll send a picture of my radio if you are interested.
