    Should serve to power a 300A, so long as the HV rectifier is changed to a full-wave bridge. The 350Z HV secondary has twice the AC...

    Do you know if they use the same transformer? If not, I wonder if the B+ sags more under load. Just a bit more internal resistance on...

    Gotta say that's outside my experience. But in the bigger picture, my experience is with stuff that's broke, or not performing. I have...

    Shockwave replied to the thread POW KW+ keying circuit.
    Looks very much like lightning damage to me. That board would normally only have low levels of RF drive on it. However, in receive, a...

    Cool. You'll probably notice the Maco tubes, look identical to the GE, because they were all made by GE. Someplace on each tube, you are...

    Shockwave replied to the thread POW KW+ keying circuit.
    The red wires coming off of the relay are short enough to not make much difference at 27 MHz. I would leave them alone. However, that...

    Good morning Shockwave, Thank you for all the good advice! I was wondering about the coax, also if you notice, there are red wires from...

    Shockwave replied to the thread RCI-29 purchase update: Beware!!!.
    I've seen this problem before when I experimented with $1.27 TO-247 MOSFETS in a 170 volt line powered linear. The best thermal tracking...

    The problem is the Ranger RT-5 finals. Biasing a switch mode MOSFET into the linear region for clean SSB use is somewhat tricky. They...

    Nope. Power is measured in Watts. Power multiplied by seconds, or minutes or hours is "energy". Think of the electric meter on your...

    Shockwave reacted to BC Coyote's post in the thread RCI-29 purchase update: Beware!!! with Like Like.
    It's completely inexcusable for any company to sell a radio that has to immediately be "tuned and aligned" by a shop after purchase...

    Shockwave replied to the thread POW KW+ keying circuit.
    One other thing I noticed is the RG-8 coax left its shield completely ungrounded. This is bad because it will radiate output power...

    Shockwave replied to the thread POW KW+ keying circuit.
    If the capacitor let the smoke out, there is a likelihood that the diode feeding it is also shorted. Check with your meter to make sure...

    Shockwave replied to the thread POW KW+ keying circuit.
    If you can only find AC in this amplifier, you've found the problem with the original keying circuit. The amplifier must have DC to run...

    Shockwave replied to the thread Diodes inline with antenna?.
    Unless you had a situation of severe receiver overload, such as somebody parked in your driveway transmitting, these diodes would never...
