[Hallicrafters] SX-32 audio amp question.

[Richard Knoppow]

     The main difference between the SX-28 and SX-32 is that 
the 32 does not have the Lamb Noise Blanker.  This was a 
highly touted feature of the 28 but was dissapointing in 
practice. I think users expected too much of it.  A late 
service bulletiin for the 28 advised removing the noise 
blanker and replacing it with a conventional series-valve 
noise limiter. The 32 comes with a diode noise limiter but 
still has three IF amplfiers and two variable bandwidth IF 
transformers. There are other differences but I've forgotten 
them and you can discover them from comparing the handbooks. 
Hallicrafters made a few receivers that were supposed to be 
very advanced but were not engineered throughly enough, the 
SX-88 being another.  The SX-28 was a very good receiver but 
many of its virtues can be found in the SX-32 which was 
significantly cheaper. Hallicrafters often adopted new and 
advanced technology but its application sometimes left a bit 
to be desired. They did best in offering high value at 
reasonable cost rather than world-class equipment. 
Nonetheless they made some very good stuff and very little 
junk.
