[Boatanchors] Collins 51J-4 power transformer, tubes

[Howard L Ritter, Jr]

As a newbie boatanchorite, I recently realized a longstanding ambition 
and acquired a 51J-4 for what I think was a pretty good price. However, 
it was a sight-unseen purchase (you-know-how) and when I got it I found 
that it has what I think is a nonstandard power xfmr. It is a 
conventional-appearing unenclosed xfmr whereas the photos I've seen of 
51Js show a canned, rectangular component. Otherwise the rig appears 
intact and clean. I have not powered it up because the replacement 
xfmr, assuming that's what it is, was sloppily put in and now hangs by 
its wires and one loose bolt and, being free to rotate around the bolt 
during shipment, took out nearby V-113, a 6AQ5.

Does anyone know 1) whether all 51J-4s had an enclosed power xfmr, 2) 
if so, a good source for a proper replacement, 3) precautions regarding 
effecting the replacement, and 4) a good source for tubes for this rig 
(and other boatanchors)?


Thanks,
