Tube Amp for 11 meters
 
I have a Nitro 300 made by Transel. Old unit using sweep tubes. D/K's (for me) 275, swings 350 rms. I would like to have a unit with a D/K of 500 (or a little more) and swing to @ 1kW > 1.2kW on AM. And I want to avoid sweep tubes. I know most responses will lean toward the DC comp builders' ( I'll not name any brand ) AC boxes but I don't want to go that route. Is there a brand out there that will do what I mentioned above and maybe 2kW on SSB, ( AB1 biased with filtering of course ) or am I limited to sweep tube technology on this ?

you can try a Heathkit SB220. I have one an keyup at 500 and swing 1000 or more on 11 meters it has to EZ-500 tubes in it.

I sure there be more posts on better tube amps....

The Heathkit SB-220.

If you're talking about AM and something around 1000 watts output, forget the SB-220, or any of the 3-500 type amplifiers, they just ain't gonna do it (4 tubes, maybe, big maybe!). Start looking at tubes with a plate dissipation capability in the 2 or 3 thousand watt range.

HF-2500DX from QRO Technologies

The best would be a DX-3 from Emtron but they are hard to find. They are made in Australia and rate about the best of the best.They do sell factory direct however.
