Re: Sunfire Tube pre dilemma

Brian,

Me too. NOS Koetsu Rosewood.

In about 1982 one of the very best pre-preamps/head amps was the Counterpoint SA-2. It used 4 6DJ8/6922 tubes, not unlike Bob's mod. But it also used 3 more tubes for regulation, and rectification. As good as it could sound, it was some what unreliable. It took a lot of work keeping it working well, unlike Bob's designs.

Most audiophiles agree that an active head amp (especially tubes) is much more musical and involving than even the best step-up transformers.

Hey Guys,

I've been out of the Carver/Sunfire loop for a while. Where can I find more out about the MC phono stage mod?

Thanks,

Hey Trev,

It has been a while. :shock:

You can't. [-( :lol:

OK, you can, but it is a closely held secret, and if we tell you we have to kill you. #-o

PM me.

Bruce :D

Trevor.

Take a road trip to sunny Ottawa, and you can listen to it.
At the moment there is only one tube pre amp with the mod and
it's at my house, in Ottawa.

Dr W is trying to recreate it, I have sent him detailed info on the mod.

Stay tuned.
