[Milsurplus] Ebay TBY now TBW

[Ray Fantini]

Ok, so that’s how it is. So tell me what was the first Navy transmitter to use the three tube line up of a 837 isolated filament oscillator 807 or 837 Intermediate amplifier and 803 with suppressor modulation?  Along with the idea of separate LF/HF bays? The TCM is something along those lines too.
The 1936 Radio Handbook, no relation to the ARRL handbook has a very similar three tube 803 output transmitter in it and think those tubes hit the market in 1934 or maybe 36 and as a side note always thought the TCK was a newer design then the TDE but what do I know.

Agreed Ray!  And yes the GO/TBW might be based on the TDE, although the TBW and GO are maybe by comparison lightweights. The TDE and TCK also require a MG set.  The 803 is indestructible! They should have never come out with the 813 although it's rated for higher Mhz.

I built up and ran a TBW for some time, sold it off a long time ago. Fun transmitter. The 803 output tube was almost indestructible! Did a video of it back in the old SD analog days at :

The GO and the TBW always appeared to me to be a light weight version of the shipboard TDE transmitter. Don’t know if that’s the case or not. For a long time wanted a TDE or TCK for playing around with AM but now days all I can think of is how much that stuff weighs.
