    Default how to build an Atma~sphere M-60

    Interesting little film from Ralph and the people at Atma~sphere
    Truth is always new, totally unknown, and unknowable. The mind must come to it without any demand, without any knowledge,without any wish; it must be empty, completely naked. Then only truth may happen. But you cannot invite it.

    Interesting.

    Heard a pair of mono ones once - boy did they run hot with a very direct sound. However the idea of OTL freaked me out so I didn't go there.

    yes no need for extra heating in a well insulated room , I'm a big OTL fan
    and I find well designed and constructed amps are as stable as anything in fact more so than some valve amps as no output trannys to damage
    mind you the 26v dc my Graaf was putting out of its right output the other day due to a faulty driver valve was a bit scarey

    Looking at that, you'd hope they were cheap as chips.

    I think he's built a few before
