The Jennen-Trio JR101 Communications Receiver
The Jennen-Trio JR101 was similar to the Lafayette HE30.

 
 
I found the JR101 to be a very unstable Receiver. It was not suitable for the reception of Single Sideband.
Over a period of time, I modified the receiver to try and stabilise the oscillator. Although I managed to improve the stability,
I finally decided to purchase a second hand TRIO JR310 Communications Receiver and the difference was outstanding.

Please note:  I  no longer have my copy of the Manual for the Trio JR310. I sold the receiver a number of years ago, together with the Manual. (I have received many e-mail requests)
