Jeff:
as far as tubes go, if those old receivers have some really odd ball tube
that was only availible from military surplus, then maybe...but in that, we
are talking probably 1940 to 1950 erra when those kinds of tubes were
readily availible.
Generally speaking, you can get nearly any kind of tube needed from either
new old stock or from companies that have remodeled the tubes or are
reproducing the older types of tubes for a fraction of the going cost for
the military surplus tubes that can still be found occasionally.
Most of the military or industrial grade tubes are sought after because they
tend to exhibit more stable characteristics, but in a receiver type
application, it isn't as vital to have that maximum stability.

So, my point to all this is that tubes are not necesarily an arm and a leg
unless you just have to have the industrial/military versions or the
original erra tubes.  Or, unless the receiver takes some crazy odd ball tube
that was only made for 8 years in the philips factory in the UK.
