Hello I am looking for an inexpensive HF amplifier that will put out 350-1500 watts. I am willing to consider anything but please don't reccommend very expensive amplifers. Thanks in advance for your help.
350 to 1500W is a pretty big spread.
With a 100W PEP rig as an exciter, I doubt I'd want a 350W amplifier. For 5.4 dB, it's not worth the effort to me.
1500W is an 11.8 dB increase -- much more noticeable. 1000W is 10 dB, not a bad compromise. The Watts all cost more once you get above about 600-800W.
I agree the AL-80B is a lot of bang for the buck, in a proven design that just works.
If you don't mind "used," I see a lot of older Alphas going for very reasonable prices -- but they use expensive tubes.
