[Milsurplus] Professionally converted radios

[Ray Fantini]

What is the definition of a "professionally converted" radio? I have seen the statements on EBay about the professionally restored or professionally aligned R-390 receivers or the professionally calibrated TV-7 tube testers and have to wonder what the pedigree of that person is? Perhaps it's my own arrogance or my particular form of dementia but I feel that if you're going to be playing in this sand box you need to put forth the effort to do things yourself or with the assistance of others like the people on this on this list server. I am very leery of any "professional amateur" operators. But maybe that's just me. Please enlighten.

Greetings,
I have a great looking ARC-5 40 meter receiver for sale. (6-9.1 mc) Black 
wrinkle looks almost like new, plays perfect. Converted for easy operation, 
it has a spinner knob installed, BNC antenna input and headphone jack all 
professionally done. Filaments converted to 12 volts. Give it 12 volts and 
+150 and you are there.
