Its good to know that there are knowledgeable people that know that the  
SX-88 and SX-73 share the SAME Tuning knob minus the skirt.I was accused by 
this  'SX-88 expert' that I have 'limited practical experience' .
Obviously he doesn't know himself  whats he's talking about.

You can't make a blanket statement like that based solely upon your  
limited practical experience. There are differences between production runs  for 
example. I have around fifty NOS .047's here that test OK for  example. My 
own personal practical experience has shown if the caps have  had any 
significant voltage on them for a period of time they will usually be  found to have 
degraded. Like I said, I tested everything and replaced the  capacitors 
that leaked. If the caps in the IF filter needed to be  replaced I would have 
replaced them. They were practically out in the  open and I was pretty deep 
into that job.

so do  the AVC and Cathode bypass caps they don't have any significant   
voltages across them either but they are plagued with leaakage  just  like 
all 
the other capacitors in the  rcvr.

That's not   correct, they tested OK probably because they don't have 
voltage on  them.

Interestingly the guy didn't replace  the  black  beauities mounted on the 
wafer switches (that control the IF  passband).They  are just as bad as the 
 
other.

Yes,  superb. Looks pristine. I'm an SX-88 novice:  what are the  unlabelled
hrome knobs beneath each tuning dial used  for?
If I had  this, plus the Tek 570 tube tester currently on  auction, I would
ie   happy.

Way too  rich for my blood, but it looks like someone did a  lot of 
detailed 

estorative work on it.
