Does anyone have access to tech manual TM 11-4000, titled Trouble Shooting and Repair of Radio Equipment? Supposedly, the later 1958 (obviously not the 1945 edition) uses an R-390A as a training example with expanded foldouts and schematics. I'd like to confirm this. --- Don Reaves R-390 list administrator <mailto:r-390-admin at mailman.qth.net>
