Atma-sphere M60 II.3-Any good for 4 ohm speaker?

Ralph is back!

Many of you may not be aware of the fact that Ralph Karsten has returned to Atma-sphere, along with his proven track record of product development, customer service, quality, and integrity. The other parties who were briefly running Atma-sphere during Ralph's "departure" in 2004 are no longer affiliated, in any manner, with Atma-sphere. I don't wish to comment further concerning details, since I don't want to see this thread closed. In short, Atma-sphere is back to the same high quality operation for which it has been known for the past 25(?) years!

711smilin, call Atma-sphere (Ralph or Bill) since they will be able to best help you with your decision. And forget about the tax write-off, which only comes into play for an amount OVER the fair market value of a charity item!

Trelja, I would check with Atma-sphere regarding the 12SX7 tube mods. I was lead to believe that this mod was not good for transformer longevity, but I may be mistaken. I was discussing several issues about my amps, and could have misinterpreted or confused information about the 12SX7 mod.

Trelja, your NOS 12SX7's that you bought, are you talking about USA or EU brands, or Chinese, Russian, or Yugo brands? I'm not sure, since you say that the 12SX7's are not being produced, so all tubes would technically be considered NOS. What are the sonic advantages of the 12SX7's over the 6SN7's? I just sent my M-60 Mk. 2.2's back for circuitry upgrades (but no A/B mode for me, thank you very much!) Hopefully, you are also using an Atma-sphere pre-amp, as well. And what are you using for speakers?

711smilin, I agree with Trelja. You will be buying a great product, while helping people who are definitely in need and badly hurting. I didn't mean to sound callous concerning my comment about a charitable tax deduction; I just didn't want you to get a big surprise from your "Uncle Sammy"!
