Basic Troubleshooting

Last Update 4 years ago

Due to the fact there are several types of rear knob available for Retrosound radios, occasionally when you assemble your radio, you will find that the rear knobs are loose, if this is the case, follow the below guide.

if you look at the control shaft from the side, you will see that the brass "sleeve" part on the shaft is where your rear knob attaches. All we need to do is push either side of the "key" or "slot" in the brass sleeve out a little.


Gently place a flat head screwdriver in the slot and give it a slight twist, then do the other side of the slot.


Test the fit of the knob and if required repeat until you get it sitting nicely.
