[Lowfer] "1000 W" Audio Amplifiers

[Larry Molitor]

Ward,
Are you going to shut down 630?  Use the existing 630 antenna for 2200 or something different?
I am struggling to do it but have so far managed to keep my 137.5 WSPR RX going mostly 24/7 so it's should be ready and waiting on you!

David,

I'm getting close to transmitting. My PA is the Hafler P3000. I've picked up a couple on Ebay. Easy to work on. . . 

What part of the world are you in? I'm looking for RX stations 'out west' when I fire up in a month or so.

I'm looking around for a high power audio amp
for some work at 8 KC.
I searched "audio amplifier 1000W" on Ebay,
and what I got was a lot of car amplifiers that
claim "1000W."  But they have no heat sinks
and 1000W out at 12 VDC we'd be talking
near 100 amps.  I don't think I believe these
things are "1000W."    Anyone know what
they're talking about?  And where one might
find a 300+W audio amp that costs less
than a house payment?
Thanks.
