[Milsurplus] KL/GRC-3030 parts needed

[wf2u at ws19ops.com]

Greetings All,

This is for our participants from the Netherlands mainly who may be  
more familiar with this set, but of course anyone with info is welcome:

I got a nice GRC-3030 a few years ago and after initial tests I left  
it as a future project. The problem was very low output, from the  
transmitter, if I recall, it put out about 2 watts maximum.
I have all the manuals for it and also some restoration notes, so I'm  
aware that they came "demilitarized" when they were sold to surplus,  
and the output tank coils had to be reconstructed. The manuals and  
some photos show an adjustable ferrite or iron core in these ceramic  
coil forms.
In my unit, the output coils are there, on the ceramic coil forms, and  
I checked the connections/number of windings and these are correct.
I think since there are no cores in mine, the inductance is low and  
this is the reason that it's not loading to the correct output.
Does anyone have complete spare output coils (I understand that spare  
coils were also available surplus) or just information about the core  
material?
I'd like to put this nice set on the air.

Thanks,
