    If I ever have a problem fixing a rig, I hope I get as much "help" as this one got.

    Oh wait! Maybe it's not yet over.

    This morning it went right into transmit as soon as it warmed up.
    I forgot I tripped over the microphone a few days ago pushing a tied back PTT wire to the ground shield.
    I do preventive maintenance on my car and my house. and get a physical.
    That's it.
    If the Valiant blows up it's only worth $350 working. I will sell it for parts.
    I don't replace parts that still work.
    I bought a DX-60 that was in a fire, everything covered with soot. I must have made over $75 selling the parts.

    "I don't replace parts that still work" You must really like taking the covers off and on stuff. I'm really glad Orthopedic Surgeons don't adopt that philosophy.

    Maybe I should replace all the parts because taking the cover off is so hard?

    Your point is well taken but we have seen a common theme here in these "Burt" threads:

    1. Burt claims to have been an electronic's instructor,
    2. Burt's responses seem to show that even a basic knowledge of Ohm's Law is either not well understood or he cannot seem to apply those laws to simple transmitter circuits,
    3. It seems Burt wants other to think for him.

    Jim EY and others have given Burt detailed servicing and tracing information but:

    W1BR: Why do you ask for advice then make asinine replies? You don't care about ham radio, but you'd risk destroying your transmitter, which would sell for an easy 500 bucks? All to save a measly ten spot on a few cheap capacitors?

    He comes back with asinine and irrelevant information that has no relevance to the problem at hand.

    So Burt, some advice. Please listen to those who understand electronics and pay attention to those responses because they are trying to help you if you will only listen and understand those responses.

    Respond to the immediate and relevant topic being discussed.

    You may think your off topic and irrelevant quips may be cute but they do not help your reputation, nor does it help others who may have similar Valiant problems.

    Burt, out of sheer curiosity I scrolled back in the thread and you posted a pic of your Viking Valiant (or your twin brother did). Yes it is in beautiful shape on the underside and very well worth keeping.
    So why do a less than half ass job at getting it working if you plan to keep it? Say you get it running, with all the out of tolerance resistors and high ESR caps still in place. Then what? do you wear a face shield and ear protection EVERY time you turn it on cuz at some point it WILL go BANG? Its not an IF but its a WHEN it goes bang. And when it does its gonna blacken the pristine undersides with szorch marks, confetti. And if your Karma is running in the minus numbers then probably a Mod or power transformer. My Son lives in Harwich Ma. Your not far from there. Whats your best price as is and I'll buy it and he'll pick it up. Do I WANT another Valiant? not really I just hate to see something that nice get all booger'd up.

    The filter caps look like fairly modern types, and not likely to "explode".

    Out-of-tolerance carbon resistors might upset peak performance, but,. again, not likely to cause an explosion.

    I would certainly run this rig without using goggles and a face shield.

    Are you going by the above picture he posted?

    You mean the one that is not a Valiant under chassis ?
