At least the SX-28 can be substantially improved with a little work. I 
havent dug into why the SX-25 performs nowhere near what its tube count 
would lead you to believe. It was the first commercial radio I bought as a 
Novice in 1955 as an upgrade from modified 80/40M Command sets and wanting 
to get on 15M. It was dead up there and a dissapointment even on 40, poor 
mechanical stability. My dad made the seller take it back and on my own I 
got a HQ-129X which I kept into the mid 60's.

The recapped and out of tolerance resistor changed, tube swapped and aligned 
SX-25 I have now hasnt done much to change my opinion. It and a SX-24 are 
strictly good looking shelf queens. OTOH, a SX-17 that is used often is much 
better and a similar design (1946) NC-183 runs circles around both. Maybe Im 
missing something basic such as a production component error.
