>> Thanks to all who help me locate the non existent Y201 crystal in my 
>> R-390 (not A). For those of you not up to date on this there is no  Y201 
>> crystal in the R-390 (not A) receiver. There is however an error  in my 
>> TM 11-5820-357-20 document. This is clearly intended to be for  the R-390 
>> (not A), but it still refers to a part that is not in the  R-390 (not A) 
>> but is in the R-390A. Namely the Y201 crystal. Be  forewarned. One would 
>> think a document written in 1961 would be fully  vetted by now. Perhaps 
>> there are later revs. of this document.
>>
>> Now on to the BIG problem. I guess I am going to get some practice 
>> working on the Geneva drive. The first IF can rack has a lifter arm  on 
>> each end. One end of this arm has a roller that rides on a cam.  When the 
>> mc setting is between 0mc and 8 mc. and as the kc knob is  turned, this 
>> cam turns and gently lifts and lowers the first IF can  rack. The problem 
>> is the roller on the end of the front lifter arm is  missing. One end of 
>> the first IF can rack gently lifts as the kc knob  is turned. However the 
>> front end of the first IF can rack is sagging  much too low and doesn't 
>> move. I'm concerned this may have damaged  either the slugs or the coil 
>> windings.
>>
>> Wish me luck!
