    Not gonna happen. You might find a used AL-811 for that price, or an older Heathkit or similar, but solid state? Not likely.

    Used AL-811s can be found for about that price, but they're not solid state. Ditto used SB-200s and similar (also not solid state).

    You may be thinking of the RM Italy solid state amps that have way over inflated values that put out very dirty signals at those levels.

    In general you can probably find one of the aforementioned tube amps for 500 bucks if you wait a while. The going price for the ALS-600 - probably the most popular economic solid state amp is 800-1000 bucks.

    They work fine for 600w PEP and 400w CW/Digital.

    Tube amps will work fine with either one. The only thing to be careful of: Many "older" tube amplifiers (mostly from the 1970s or earlier) have higher voltage or higher current keying systems that can be incompatible with modern SS transceivers, even including some transceivers using relays. Always check the "maximum keying voltage and current" ratings for your transceiver, and what is required by the amplifier.

    ANY older amplifier can be modified to accommodate modern keying systems, but you may have to do that yourself if it hasn't already been done. Modern amplifiers don't have this issue. None of the Ameritron amplifiers have this issue.

    Were it me in your shoes, I'd "save up for" a good used ALS-600 with power supply. Very small footprint,
    and pretty bullet-proof from everything I've read. I've never run any sort of amp but I have flirted with the
    idea of the ALS-600 maybe at some point.... some day when "I can hear them" - but for now, 100W gets
    me by with the electrical noise I deal with most of the time.


    ps - very nice station! I love the old Trio/Kenwood rigs - had all of those myself once upon a time
