    4, yes I am aware of the mismatch. But it will work, just like it did for Hendrix

    I’m thinking about building one after I finish this build for glogulus. I’m wanting to do KT88’s and use the 560 volt taps.

    I built one with two KT88's and used the high voltage taps. But I did use 3k screen grid resistors. It sounded glorious!

    So can you run 560V on the plates of modern KT88s, just not modern KT66s?

    So @Bluesful what is the expected delivery time on your new beast? I'm anxiously awaiting the new video clips. This thread has had me cranking my mini-marshall a bunch lately in anticipation.

    Build time was quoted at 18 weeks.

    I can remember when the start was though.

    I recall calculating it out at the time to around the end of November.
