[Milsurplus] Boulevard Receiver

[WA5CAB at cs.com]

I think a lot of list members, when they learn that a shipboard set is AC-DC, 
suffer from a knee-jerk reaction that equates AC-DC with cheap 50's vintage 
5-tube radios.  As it happens, cost (usually) had nothing to do with it.  At 
the beginning of WW-II, virtually the entire merchant fleet and most combatants 
were DC ships.  Most of those ships (those that weren't sunk) remained in 
service beyond the end of the War.  USS Texas (BB-36) is a good example.  It had 
(has) 230 VDC mains.  Consequently, radio equipment was designed to operate 
from a wide range of supply voltages, including in the simpler receivers and 
transmitter-receivers 115 VAC/DC built in supplies.  Technically, many of the 
popular (with collectors) WW-II vintage shipboard receivers and I think all 
transmitters were AC/DC.  Including the TCS, MBF, TBY and TCZ.  And most anything 
built by Mackay would have had to have been or the ships they could have been 
used in would have been severely limited as they mostly supplied gear for the 
merchant fleet.

USCG, which has always been at the bottom of the funding food chain even 
below the Navy, simply had to carry the requirement longer than any other agency 
or department.
