Amen. Put it in storage and wait til you get back. If I were closer, I would do it for you for parts cost only, because you are in the military. But it would cost a ton to ship here, and it could be damaged in shipping.
I agree, if I had the time I would work on it for you for parts cost. There are a few reasons for this; 1) you are active military and you folks hold a special place in my heart. 2) This was your grandfather's and you honor him by restoring and using his radio.
Going through the radio for a restoration is just a series of steps. a) recapping the radio. b) testing/replacing the tubes c) alignment d) cosmetic restoration. The '129 is a pretty straightforward receiver design and is a good band-cruiser. In it's day it was a highly rated receiver (not as good as a SuperPro or the later Collins R-390) but it stands well on it's own. (better than any stinkin' Hallicrafters <j/k>).
If you just bought a 129x it "is just a radio". This particular radio has a special meaning that has not been washed away by the anonymity of time.
