I trying to decide which TUBE amplifier for hf and 6 meters to get I have a Alpha 8410 now would I better to hold on to it and buy a 6 meter Alpha or sell it and buy a OM or Acom.
I would like to hear your thoughts. I am confused at this point, I have read all the reviews.
I know I want 6 meters.

I use to own the 8410 and the 8406. Sold both and bought the OM-2000+. No regrets,. Read my review  at EHAM into the reviews section on the OM-2000+.

Well its not a tube amp, not sure if there is a particular reason why you need a tube amp, but I use an Ameritron ALS-1306 and it will do 1200watts all day long on 6 meters and I have been told I sound better than I do on my two other tube amps with a perfect tune across all the bands.

Just another option for you to consider.

And here's a voice for Acom. I had an Acom 1000, and now a 1500. Flawless operation and super easy to tune. Personally, I see no need for two expensive amps (Alphas 8410, 8406) unless you plan on two dedicated stations. If you're considering only a legal limit tube amp, IMO sell the 8410 and go with the Acom 1500 or OM2000+...both solid, reliable, fast tune, under $4,000 amps. BTW, Acom is coming out with the 2100...same tube as the 1500 (4CX1000A), but with a beefier power supply for continuous all mode legal limit. Good luck with your choice.

I agree with the previous poster.  I have had Ameritron and TenTec amps and currently have an ACOM 1000.  It is very well built and with the aux fan it runs 1000W key down all day.  I don't need more than 1KW and the Russian military tube that it uses is reliable and  cheap.  The 2100 should be interesting as soon as it is approved for use in the USA.

However, one has to remember that in general, tube amplifiers will have lower high order IMD products - the ones that really screw up other people - than SS amps unless special measures are taken, such as pre-distortion or other wide band feedback techniques.
