Ed, thanks for pointing out the "voltage reducer" on BAMA.  I built it today, 
and it has made a noticeable improvement in AGC action on my SX-130.  In 
addition, the selectivity/BFO (regeneration control) now works the way I 
think it should on AM and CW, probably due to the reduction in B+.  (No 
regulators in these two receivers.)

I actually ran both receivers off the transformer.  If my math is correct, 
each radio runs less than .5 amp (<50 watts each), so I should be within the 
3 amp rating of the transformer.  I plan on building another for my HT-40 
transmitter rated at 175 watts "power consumption" which should be around 1.5 
amps.  The transformer should still be in the ballpark unless I'm missing 
something?

Any comments?
