    Hello all,

    I have no provisions for 240 VAC in the shack. I can't pull a 240 VAC circuit into my shack without taking out a second mortgage on my house. That being said, any recommendations for an amp that will reliably run on 120 VAC. I realize it will be reduced output of probably 500 watts or less, but it's better than 100 watts that the rig puts out. Probably the newer solid state amps may be appropriate, but I have read a few reviews of some of them that have problems with blowing finals. I sure don't need an amp with a poorly engineered solid state final circuit.

    Tubes are getting harder to find or expensive.

    Pro's...Cons ?
    What are your suggestions or experiences ?

    I’ve run an SB-200 or AL-80b on 120v for years with no problems. 600-800w PEP easy.

    You’re not going to run 1500w RTTY on a 120v circuit, but you can pull some decent power from a normal circuit that’s otherwise lightly loaded.

    I can recommend an AL80-b with no reservations.

    Just out of curiosity, is that a 15 or 20A circuit?

    SHANE,
    SAFETY FIRST

    WN1MB BROUGHT UP A GOOD POINT.

    DO YOU HAVE A 15 OR 20 AMP CKT
    GOING TO YOUR SHACK.

    I HAVE BEEN RUNNING A AMERITRON
    811H FOR MANY YEARS.

    I HAVE A DEDICATED 120 VOLT / 20 AMP LINE FOR THE
    AMPLIFIER

    ALSO, DURING THE SUMMER MONTHS
    I RUN AN AIR CONDX TO KEEP THE SHACK
    COOL. I HAVE THE AIR CONDITIONER ON
    A DIFFERENT 20 AMP LINE.

    AGAIN, SAFETY FIRST.

    15 amp circuit but pretty close to the panel.
    Many people run portable electric heaters on 15 amp circuits. The amp draws less than one of those on SSB.

    It is a 15 Amp circuit.

    Just connect two of your 120v outlets in series for 240 volts :eek:

    Have you even looked into it? Gotten a couple estimates for getting it done? I had my whole kitchen and garage rewired and added a 240 line and and an extra 120 line to the shack room for just under $2,000 a couple years ago.

    Short of that, I had an AL-811 for several years that worked just fine for me on 120V. An AL-80B is what I have now on 240V but it would be fine on 120V.

    So just plug one outlet into another?:eek:

    You guys are joking, but I have seen a college ham station that used two 115VAC outlets that were on opposite legs of the 220 feed to get 230VAC to run a Hunter Bandit...
