[Milsurplus] Let stir up the hornets nest!

[Mike Hanz]

That's a fair question, Mike.  To me, the APA-10 is in a somewhat 
different class than a BC-224-A or other 1930's comm set.  The original 
conversion to 60Hz is *not* trivial, so if it is operational, the 
deconversion would depend on two things - the availability of an 
original 400~ transformer, and the degree of metal patching required.  
For that set, I'd be tempted to leave it as is, especially if it's 
working well.  It's a neat looking panadapter, even if the 30MHz 
position requires a bit of manual sweeping to scan the full band.  Mount 
it up high on your shelving and you won't see the 60Hz transformer on 
the back... :-)
