[Milsurplus] WWII Navy RAL-8 Receiver Project

I ask, why is it desirable to improve the high end
audio response of the RAL receiver ? Lacking AVC,
it's not what you'd think of as the most practical
HF broadcast

listening receiver. 

Also, some years back on this forum I read about
an RAL that had been converted ( sorry, for that
word ) with FETs replacing vac tubes..would like
opinions, would such a project be 

sacrilegious?  There will come a time maybe when
such considerations HAVE to be considered, as the
only tubes to remain in production, I think, will
be ones 

particularly for the audio market. 

---------------

While refurbing the RAL, I dug-out 10 untested 6D6
tubes, since the 

Detector tube was flat.  4 of 10 were bad; three
with low emission

and one with gas.  

Is it just "luck of the draw," or are a large
percentage of tubes

testing as "bad" than did where we were younger?
Are

they "gassing-out" on us?  Thoughts?

rebuild,

Visions of a grey RAK, grey RAL  to go next to my 

sweet grey RBC and the grey RBB that's waiting for

me to find it and rescue it ;-) :-D
