  1. JuneauMike replied to the thread Zener -- dropping voltage oddity-- 5F11.

    Professor, I think the lesson here is that the bias is the wild card. The zeners won't be properly taxed until you bias the amp to its...

  2. JuneauMike replied to the thread Zener -- dropping voltage oddity-- 5F11.

    Dude, thank you so much. So previously I was fixated on the effects of the zener on that B+ node. But i wasn't factoring bias in? And...

    Hmm, those plate voltages were plate to ground, so I guess that reading is not so useful. Sorry bout that, I should have done plate to...

    Ok, this is some next level stuff for a newbie like me. But I can see the 6v6 working with the zeners here. @RLee77, thank you so much...

    Yes, I sensed the disturbance in the Force had subsided and balance returned to the universe. That must have been Uncle Doug.

    Oh well, if you've got the lamp, you're pretty much done. ;) If its an LED, wouldn't you drill out the lamp base and run the little LED...

    I of course have never done this.... bwaaaa haaaa..... d'oh, crap.... guess I did... again

    Thanks @RLee77 and you are correct, all of those min/max readings are in mA. Typing on a tablet is a pain. Overall, do these current...

  9. JuneauMike replied to the thread Zener -- dropping voltage oddity-- 5F11.

    Yeah that's exactly what the coroner's report on my dead fuse says. I wasn't thinking methodically and it bit me. I've since tried to...

  10. JuneauMike replied to the thread Zener -- dropping voltage oddity-- 5F11.

    Ok, I'm done for the night. Feel more confident in my data. Hopefully someone can explain it to me. I could link the rectifier with B+...

    Ok, my meter seemed to stabilize the longer the amp ran. I used the process i described in post #89. I think this is better data:...

    Digital MM's don't care about polarity, they just throw up a minus sign. No big deal.

    Are you saying by having the black COM probe clipped to the rectifier side (and red 400mA probe clipped to the zener cathode) could have...
