[R-390] TIRED OF READING ABOUT CARDBOARD SPEAKERS

[DJED1 at aol.com]

I've got a bit of a problem because my wife has her own ideas on winter  
projects.  I'll be rebuilding a bathroom for her, so my radio list has to  be more 
modest:  I want to try and fix the warble in my Progressitron PTO  and put it 
back in the radio, then set up a jig to calibrate the Cosmos.   I've done it 
in the radio a couple of times, but my hands and eyes get awfully  tired 
working in tight spaces.  My concern is that if I want settability of  100 cycles 
on the PTO, I need a fixture that will read out accurately to a small  fraction 
of a degree.  After that, I want to clean and lube the geartrain  in my 
SP-600.  Anyone know of a reference to tearing down the geartrain on  the SP-600?
