[BC] HT Transformer

[David Reaves]

Not totally unknown, at least to this former Chief Engineer.

In the early '90s, when upgrading facilities for the new (at the  
time) Master FM Antenna at the Empire State Building, we decided to  
get a new 10K transmitter, instead of just derating Z100's existing  
Harris FM20K.

We bought and installed a BE unit, as did most of the other Empire  
tenants (IIRC, about a half dozen). Our new unit's plate transformer  
failed very shortly (literally) after installation. Its replacement  
failed about 6 months later.

Even though it happened twice, I just chalked it up to a bad luck  
experience. BE replaced both for free, with shipping, though the  
hassle factor left a sore spot. Moving those beasts is a true PITA.
