   Hi,   
      
   I have Rockola 460 and had the same problem, exept my machine selected only   
   A-sides. The read-out arm didn`t care about the pins at all, no matter what I   
   did:   
   - checked fuses, didn`t replace any relays or nothing, just pulled them off   
   once, checked pins for warps and placed them back   
   - flipped the wobble plate pins up and down by hand thinking they are stuck or   
   something   
   - checked solenoid on the wobble plate and lid near pushbuttons    
   - cleaned the copper contact stripes from both sides of the plate    
   - took read-out arm off, cleaned all the contacts with sandpaper, same thing   
   for the other side: little tricky trying to get paper under the contact clips   
   while all parts around in place, but can be done   
      
   After doing all this, it still refused to select B-sides from any of the   
   records. And after triplechecking and still no B-sides, my brains started to   
   prepare for meltdown. These machines can cause you a real headache but in a   
   good way, an obsession too!    
   I didn`t give up, at some point the whole machine would stop and do nothing,   
   blown fuses etc.     
      
   But when I was about to flip my lid, I noticed - while the read-out arm was   
   doing its "normal thing"- rotating endlessly around the wobble plate - that   
   under the scan switch there`s a microswitch. That`s the A-B switch and from   
   that goes a lever towads    
   the back wall, right between the carousel and the mech frame, bolted from the   
   other end near the basket motor. At the right side of the carousel there`s a   
   drive gear which has two grooves in it, outer and inner and a small gap   
   between them. Somewhere in    
   the middle of the lever is a small " knob" that rotates in the grooves: outer   
   groove is A-side and when B-side is selected, the " knob" should slip to inner   
   groove from the little gap causing the lever to rise a bit allowing the A-B   
   switch to connect.   
      
   My jukebox had this problem, the "knob" never slipped from the gap to the   
   inner groove so no B-sides for me. Took the lever off: backbolt off and with a   
   little force pushed the lever first to right to get the knob out of the   
   groove, then downwards to    
   release it, it`s a tight fit but you dont`t have to take extra parts out to do   
   it. Foud out the knob was so jammed with old grease it was hardly moving:   
   cleaned, oiled and re-assembled it and it helped. Your problem maybe the   
   opposite, knob is constantly    
   rotating the inner groove: check the lever, knob may not be able to slip to   
   outer groove. You can test it by pushing the lever down from the end by the   
   micro switch while read-out arm rotates.    
      
   What comes to the sound, check needle. Probably you`re going to need a cap kit   
   for the amp as the capacitors are perhaps worn out.   
      
   Hope this helps, have a good one and good luck!
