[Boatanchors] RBO reciever question

[RKofler@aol.com]

My favorite SWL receiver is an EH Scott SLR12-B, which I have completely 
restored. It does an excellent job. As far as I know, there are only minor 
differences between the RBO & SLR, such as placement of some components, such as the 
power supply filters. The RBO has a tuning lock which the SLR does not. These 
rcvrs were shielded so that German U-Boats couldn't home in on the radiation 
of the local oscillator. SLR stands for Super Low Radiation. I run my SLR with 
the chassis slid out of the cabinet a little bit because they were pretty 
stingy with the ventilation louvres. The RBO is USN, and the SLR was used by the 
Merchant Marine during WWII. With 6V6's in push pull, the audio is unsurpassed 
in a SW RCVR.

There! Now you probably know more than you wanted to about these fine RCVRs.
