[AMRadio] Legal limit AM amplifier, homebrew

[Ed Sieb]

Just two comments on Rick's response...

First, while not quite 6dB, a 300W AM carrier is still a substantial 
difference from a DX-100 at around 100 - 125W.  I'd go for it. 
I hear guys running 300W all the time, and with a good 
antenna, they "strap".

Second,  I have 40 years of high power parts here in Ottawa.  
You name it - big coils, big oil caps, bread slicers,  transformers 
of all types, including monster filament and plate transformers, and... 
MODULATION transformers  from 100W to 1KW!!!   The small stuff is  
relatively easy  to ship, but the large transformers are pick up only.  
Yeah... I know...  who wants the hassle of crossing the border just to 
pick up a piece of iron.  But if you're willing...
The price... cheap, and  I mean cheap.   I don't want to carry this 
stuff to my grave, and I really need to lighten up and liquidate "junk".  
Aynone who want some good stuff, email me and we will organize 
something.

Bernie makes a good point that the difference between such an amp and 
the barefoot output of the DX-100 on AM probably will be just barely 
noticeable, if at all, on the other end.  The DX-100 is rated 100-125 
watts out on AM, and there is a general guideline that says if you 
can't increase power by at least a factor of 4, it's rarely worth 
it.

Now... where's a good place to get a power transformer and filament 
transformer for such a beast?
