[R-390] R-390A Crystal Osc Deck Removal

[Joe Connor]

How tough is it to remove the Crystal Oscillator deck without removing the RF deck? I see that the Y2K manual describes the process in some detail. I think I will be faced with this task right after Christmas.

I have an EAC blue-striper that I got working very well about 10 years ago. A couple of years ago, I turned it on, there was a small wisp of smoke from the crystal oscillator deck and the radio stopped receiving. I noticed that the 6AK5 in the crystal osc. deck did not light even though it tested good. I have avoided the repair for several years but now I think (hope?) that I am going to get a new crystal osc. deck as a Christmas gift. Undoubtedly, I will be asking you all for help when I tackle that job. Working on that set is going to be a whole lot different than working on the Hammarlund Comet Pro that I am currently restoring.
