Yes.  The V-7 thru IM-18 series of VTVM's were essentially the same 
electrically.  I have PDF copies of partial manuals for both the V-7A and 
the IM-11 and the components in the power supply area are of identical 
values.  Per the IM-11 parts list the transformer part number is 54-23.  In 
a Heathkit transformer cross reference document it shows that part number 
for the V-7A and the IM-11.

Can anyone tell me if the transformer in the Heathkit IM-11 VTVM
is interchangeable with the transformer in the Heathkit V-7A VTVM?
