Hi Brian,
	You do not need to remove the turret to do any 'normal' service work on 
the SP-600.
	Take a look at <http://www.hammarlund.info/SP600svc.html> for an 
article be Ray Vasek, W2EC, several yrs ago and has given me permission 
to have it on the Hammarlund Historian website.  You may find j;ust what 
you want in there.
	The electrical power switching from single to double conversion is done 
by the small single pole wafer switch that is located on the back of the 
turret box, under the chassis.  Maybe there's a simple solution right there.
	If you have any questions once you get into it, I'll be glad to try to 
help.

I know there are problems with the 3.5 MHz oscillator and second mixer.  Is there an easy way to get to the components under the associated RF chassis?  It looks like removal of the bandswitch turrent at minimum is required and that appears to be a formidable task.  Any comments appreciated..  Thank you.
