> I don't know where to get KT88s but aren't they similar to 6V6s?
In the manner that they are a beam power pentode, yes they're the same.  
However, comparing a 6V6 to a KT88, is akin to comparing a Volkswagon to a 
Cadillac:  Both will get you down the road, but the KT-88 will get you there, 
IN STYLE! 
Know a guy who homebrewed an audio amplifier (stereo) with a pair of KT-88's 
in each side.  Then, he built enclosures that would handle it - in his house, 
6' tall, by 4' wide, with tweeters, Mid-range and Woofers (18" woofers, at 
that!), played with the ports, and all... came up with a pair of NICE 
'towers', that would push you out of the room, with absolutely NO distortion!
I mention this, because there's output on the thing for a backup 
"speach-amp", should his main audio supply fail, for the AM rig.

He's a purist, alright.  Only guy I know that used a pair of 6146's as audio 
output tubes.  Drives a pair of 833's with 'em!

remember, Bob - a solid state, or "quasi" AM (with carrier 
unbalancing/injection) should only be loaded up to 1/3 of what the normal 
output rating is.
The components of an AM signal (I know you know, but some might not) are 
Carrier, USB and LSB.  That's where the phrase DSB (Double Side Band) came 
from.
So, for of the audio to be conveyed by the carrier, the carrier must be 
reduced to a point where 100% of the signal can get through.  The upper limit 
for this to happen is 33% carrier, and 66% audio.  Leaving room for a little 
head-way, a safe bet would be around 25w Carrier, the rest audio (use a scope 
to adjust), THEN bring in the amp, and amplifiy -that- signal.

Gosh, I wouldn't know - but you could probably post something in the HAM_SALE 
echo, and someone could possibly help you, there.

That 930 ain't no slouch, either.
For a recommendation, I've laid my hands on the New Kenwood, and the AIP 
(Advanced Intercept Point) is a -neat- feature!  That and DSP built-in make 
for recieving SSB signals fairly nice!
Nothing beats an old HQ-180, however, for AM reception, as far as I'm 
concerned.  Hang a big 18" speaker on the output of that thing, tune
in a broadcast station and entertain your neighborhood! .
