Top, I think.  Maybe soon you'll have a second radio to compare with :-)  I 
suggest you add a length of much more flexible wire to that lead to avoid 
damage to the lamp socket or broken wire strands.

Be very careful.  If you have a larger knob than normal, you *may* have an 
R-389 tuning knob. These are definitely larger, and have a clutch built 
into them that prevented disastrous damage to the R-389 PTO.  If this is in 
fact what you have, and you have no R-389, I'll be glad to swap knobs with you.

The MC an KC knobs I have seen on R-390...'s are all the same size.
