    Ok, John, the guy from Courtland will be meeting me on Wednesday. If you want me to fix your amp see if you can get me the amp to him tomorrow. Lou

    That's exactly what you need . . . somebody local to:

    a) fix this simple fault
    b) show you how to tune it up

    Glad you got some help

    Merry Christmas !

    well i said i would report back so here it is - it had a bad tube and the wrong tubes, Cetrons are not desinged to be run horizontal so i put in new taylors. thanks for all the help!

    except, Cetrons were used by Yaesu originally.

    Yes, Cetron 572Bs ARE designed to be used horizontally . . . and as mentioned, they were the tubes chosen by Yaesu and fitted in all their Linear Amplifiers !

    So guess you just had a faulty tube.

    The "Taylor" tubes are made in China, and are replicas of the CetronTubes. (i just bought mine direct from China, so they weren't re-branded . . . but much cheaper!)
