    Just wondering what would be the smallest tube amp would be watt wise? Is it the 4CX-250B? Possibly looking into a small tube amp for the base. I had a 4CX-250B box awhile ago. Just seeing if there is something smaller out there.
    Should have stated this was for 11 meters with SSB capability.



    ****Please move to CB amp section!!!!

    I've seen many single tube home brew amps. one 6LQ6 I believe, doing 40-50 watts. SSB is the addition of a delay circuit.

    Manufactured smallest amp? I dunno

    RM makes the KLV-200 Base. It has a single EL509 tube and will do 100-125 watts SSB cleanly.

    Yeah,
    I'm just looking to get out of the mud if need be. 100-150W should do the trick. Don't want to disturb the neighbors, you know.
    The KLV looks like a nice little amp. 220V though. I would need to run a dedicated circuit.

    The model that is sold here in the US is 110 volt, not 220.

    Does the KLV-200 vip need to be modified for 11 meter use. This would be the perfect amp for my shack. I could also use it on HF.
    Also, availability. Know locations of US sales?
    Thanks!

    I know this is an old post, but i have a Kris Boomer two tuber, 60 watts or so low drive 11m amp with good tubes. Got it from 15minigrass. Works great. That is about the smallest I have seen.

    I still have a "Jewel Box" that uses a 6BQ5 and Puts out about 8 to 10 watts carrier and 40 watts peak (AM.) Not so hot for sideband. :) They did make a version using an 8417, similar to a 6L6 that would put out around 50 watts.
