I don't  think you'll find much similarity between the 340A and 357 WJ  
receivers.  The 357 is tuned with an air variable capacitor and the  340A 
with a voltage variable capacitor diode. As far as the stability of  the 340A 
I found it poor compared to the  357.

Hi John
 
Thanks for the correction....and whoops:-)
 
Whilst I was offering the suggestion of similarity more in terms of  
operating priciple rather than actual circuit detail, and thinking the  357 manual 
might be better than nothing, I did assume the 340A  would also have physical 
capacitive tuning.
 
I must admit though that I based that on the external physical similarities  
between the 340A and the DMS105, with which I'm more familiar, so perhaps not  
the most scientific of deductions.
 
That'll teach me to judge things by appearances:-)
 
regards
