[AMRadio] HRO-5 and HRO-7 Coil Compatability

[W5AMI]

Does anyone know if the HF Osc section of an HRO-5 coil (specifically coil
C) could be mounted in a C coil set for an HRO-7?  I have a C coil for my
HRO-7, however the HF Osc coil form has melted and deformed to the point
it's useless.  Don't ask how it got melted ;)  I'm not having any luck
finding a C coil set for the 7, so I'm wondering if I could open up more
possibilities by getting a C coil for the HRO-5.....  I can't find any
circuit data on the HRO-5 coils to compare to that of the 7.

Thanks & 73
