[ARC5] Anybody have a MD7 for sale?

[J Mcvey via ARC5]

I have finally collected all of bits and pieces needed to repair my poor old ARC5 transmitters. These radios may have won the war, but lost the peace!  The only major part missing is the MD7 . I can work around not having a control box, but having no MD7 is a problem. 


BTW, I recently acquired a very decent original BC-455 to use instead of the heavily modified one that I am still trying to figure out what was done and what tubes it uses. I am curious about the mod and want to see how good or bad it works the way it is.
I disconnected and spot-checked some of the cap for value and ESR on the "new" one. Surprisingly, everything looked OK, so I fired it up after cleaning and inspection. Works as advertized 70 years later! 

Do you guys automatically recap the ARC5's or replace as needed? 

I re-stuffed the "pot caps" or bathtubs or whatever you want to call them on the disaster BC-455 since it had apparently been stored in damp conditions for many years. Those were a bit leaky.

My BC-454, which I have owned since I was 11 years old, also has the original caps and works well. The only thing I ever did to it was remove the LV line choke and disconnected the lower end of the screen divider cicuit ( I think I was using too low of a b+ at the time.) . I have subsequently restored the choke and divider to  run it on a dynamotor which only provides 210V of the 250V spec, but does the job none the less. Other than that, It has all of the parts as they were when it came off of the assembly line.
Even as a kid, I thought these radios were too cool to hack up.
