    Anyone ran into this with EH power tubes?
    Is there a way to calculate the adjustment to EFB board to bring trimmers close to center point while tube current is set to 35ma?
    I had no issue with old original Fisher tubes but they just keep floating the current, so I replaced them. Sure enough, EH current does not fluctuate. It's just too high and maxed out.

    I think Dave advises either changing the caps or resistors (I can't remember which) on the IBAM board to get the adjustment in the middle. Check with him.

    How do I send PM?
    I couldn't find this option. Is it for subscribers only?

    Now they are call conversations. Either click on his name in the avatar, OR scroll up the page to the top RIGHT SIDE on the bar next to your name you'll see "INBOX". A drop down box called conversations will show up. Click on that and follow the boxes.
