have my  MLA2500 up for sale on QTH.com and I received a query as to 
whether the 10  Meter mod had been done.  How do you tell other than trying 
to load  it up on 10?

Bob, The band switch should go one click beyond the 15 meter  position.  
There should be a wire from the band switch on the 10M contact  to the plate coil. 
 It should work on 10 meters. Some Dentron amps had a  filter in the coax  
line to the cathode of the tube which had a filter  which grounded frequencies 
in the 27-29Mhz region.  That filter must be  removed or bypassed.  On many 
occasions the filter was NOT shown on the  schematic but WAS there.
