My latest upload is the receiver with the right knobs. On my first upload the receiver had the wrong knobs.
There seems to be some confusion about the RA153 and RA253. The RA 153 is said to have one RF knob. The RA253 has 2 seperate RF volume knobs. However my receiver has an id plate marked RA153 and has 2 RF knobs.....
