Internal views of a
Henry 1KD-5
This unit looks like it served a good
hard life.  Many part changes and some mods.  Every licensed ham
operator has the privilege and joy of repair, modifications and operations of
their gear.  It is a great hobby.  
I did not apply power.  I feel
this unit needs a complete disassembly, compared to factory diagrams,
de-modified and restored before any juice (EMF) is to be applied. 
Therefore I have no idea how the output tube would perform.
