    I believe I calculated the resistance of the meter to be 500 ohms.

    I received the meter Saturday and got back to the amp today. I installed it. It is from W1QJ above very very nice OM. Before i buttoned it all up a ran voltage check 0-1 vdc across the 1 ohm resistor terminals. Tracked perfectly. Old meter with the same test was dead so this will clear the no IP reading.

    thanks for all the help. I'm tied up today but hope to build and fire up the amp, exciter, watt meter and load in the next day or 2. and I will let everyone know the final outcome. I repair a lot of radios but few big amps. When a 1kw amp's current meter is pegging I look for thoughts before I proceed. There is a local repair market for amps but I will not work on them for CB'ers just Hams "with call signs". Funny story: About a year ago I had a local guy call me said he heard I repaired radios and ask about fixing his SB-220. I asked if he was a ham he said quickly.. YES! I asked what's your call sign and are you good on QRZ? He said he could not remember it. You can't make these things up.

    Amp works great !
    final tally of issues.
    3-500Z filament would not light. purchased a new pair of tubes from RF Parts.
    replaced 1 ohm resistor (open), 1.5 k resistor (brunt), and IP meter (shorted)
    also replaced the 5.1 v zener as a precaution
    Thanks all.

    All you have to do now is polish it so it shines!:)

    And maybe pray for better propagation.:p

    The 922 is a beautiful Radio! Looks even better now that it is working.

    Don't throw out the old meter. I'll pay postage to keep it out of landfill.
