[Milsurplus] TBS question

[Marty R's GI-stuff haunt]

Bob et. al.  The LST-325's TBS is the only one I've seen

It HAS to be the world's largest transciever.  HAS to be.

I submit it's the reason so many 808 tubes wound up in surplus as nothing 
else I've seen ever used 'em.  Since TBS a Radiomarine & 808 RCA, it doesn't 
take Perry Mason.

TBS ran 60-80 mcs which was 1936 super-secure UHF.  Had acorn tube front-end

Must weigh 200#s for ~40 watts out... that's a hip shot & needn't be
since I've a TBS book.

Now MBF musta come in '45 since 7 pin mini.s there like 6AQ6 which I didn't
know were in print then.  It, like MAW, raises question why it dint get
a JAN tag.

MBF clearly built for what was then an often-found seagoing power
system.  110VDC.  And there was plenty of it on LST-325, at least 1 GMC
6-71's worth.

Why DC?  Short runs made on-ship transformer needs go away, variable 
speed motors easy, & blacksmith could learn 'electric craft' overnight.  
None of that steenking phase & power factor thinking req'd.

And don't forget the electric industry was only 30-40 years old in 1940 & 
110vdc was still everywhere on land.

Plus, as someone sed, it was the pre-ww2 US seagoing standard.

Sed b4, MBF gave all smaller vessels chance to talk to blue-water
ships

NOW...

If you're gonna use ur MBF on 6M AM 110vac, use an isolation xfrmr

Bob putting that TBS on 6m & sticking a MBF in an LCVP appears
a swimmingly gud idea.

Pun intended

(anyone have just a MBF schemat.?  That's presently enuf for me)
