    I'm researching output tubes for some projects I'm hoping to
    finish (experiment). I'm reading up on the tube data and Z-out.

    My short question, if a 6L6 is 5000 Ohms, are two of them
    added up for 10,000 or divided for 2500?

    Also, are 6V6 close enough Z to be used on an OT designed
    for 6L6?

    Part of why I'm researching this is that I'm finishing up a
    Deluxe Reverb type thing, and I have a 50watt 6L6 Multi-Tap
    OT I'm wondering if I can use for this build.

    Ahh, Ok, that makes sense then. Thanks OTM!

    I was looking at Z-Out thinking that's what I needed to match,
    but looking at the tube Data on Duncanamps it looks like I
    should hav been looking at Ra.

    Duncan Amps 6L6 Tube Data

    I'm writing down this info for future reference.
    This also helps me understand why when you swap tubes
    from 6L6 to EL34 you are supposed to switch which output
    tab on the OT to use.

    That was one of my goals of things to understand so I could
    pick through the OTs I have and find the correct one.
